“Tenma’s here,” your mom calls up from the kitchen.

The announcement is unnecessary because Tenma has yet to learn how to walk quietly, stomping up the stairs to your room.

His face is set in a scowl too, dark curls and dark eyes giving him quite an evil aura.

But you’ve known him long enough not to care about that.

“Grab a scarf,” you tell him as soon as he steps through the door, “I’m playing wedding.”

“Not again,” he groans, though does as he is told. The pink scarf he picks has hundreds of little coins sown to it, chiming as he wraps it around his shoulders and moves through the room.

“I’m a Djinn,” he exclaims, “I will curse you.”

“Djinn’s don’t curse people! They fulfill wishes,” you correct him.

“Fine,” he huffs, “What do you wish for?”

“I want Tenma to play the husband.”

“Not again!” He groans, throwing his hands in the air.

“You have to!” You declare, “Djinn’s always have to follow their master's wishes!”

He huffs and whines and begs but it’s no use. He plays the husband to your wife.

“Can we play outside now?” He asks as soon as you kiss his cheek and declare the marriage official. “Mom brought my ball.”

“Fine,” you decide to be nice today. “But don’t kick it too hard. I don’t like that.”

“It’s so weird that you’ve got a boy as a best friend,” Asuka exclaims. Your small group of (girl)friends has gathered in your favorite spot, overlooking the garden and the big open space below. Tenma’s playing Ball with a group of boys and he’s easy to pick out, he’s always the smallest in any group.

“You think so?” You ask back, taking one of the strawberries Sango brought for lunch break today. “It’s not like I had a chance. Our mothers are best friends. He’s basically my annoying twin brother.”

“Do you think he’s cute?” Ryo asks, looking up from where she’s painting Tomoko’s nails.

You consider this for a moment, look down to where he’s running around, red-faced and panting. He’s not ugly, that much you can tell, but cute?

“I don’t think so,” you say, because it’s better than to admit that you don’t really know what cute really means for a guy. You think babies are cute, but that’s not the same thing, right?

“I think he’s cute,” Ryo admits easily now that she thinks she knows where you stand. “Can I ask him to be my boyfriend?”

“I mean you can ask,” you offer, feeling a little weird that she asks you in the first place, “but I don’t know what he’ll answer you. I bet he still thinks girls are gross.”

- 10 -

“I think you’re getting a little too old to be sharing a bathtub,” your mother announces after Tenma has left.

“We weren’t sharing,” you explain, drying your hair. “We were playing that he was my magical shapeshifting dog but he rolled around in a mountain of dragon poop and I had to give him a bath. He pulled me in when I was almost done washing him.”

Your mother sighs. “Aren’t you getting a little old for those stories too?”

You tense and she notices right away.

“Dear, I didn’t mean… if this is how you want to play, I’m totally fine with that. I was just wondering…”

“How else are we supposed to play?” You ask, unable to keep the agitation out of your voice. “Am I supposed to kiss him and hold hands like the other girls in my class are pretending to do? Or play Volleyball the whole day? Or just do our homework and study, study, study until we fall asleep? Or play video games that you don’t like because they make you dumb? How are we supposed to play?”

Your mother sighs again, lowers herself until she’s sitting crosslegged on the floor next to you.

“Come,” she says, opening her arms until you crawl into her like you used to do. “I’m sorry. I know, as your mother, I should say and do all the right things but that was pretty stupid of me. Can you forgive me?”

You nod and she pulls you in a little closer, kissing your damp hair. “Now tell me, what do you like to do? What’s fun?”

You lean into her, the familiar smell and warmth, and let yourself open up.

“When I come up with a story, Tenma always makes it bigger. Like today, when I said: Do you wanna play my dog, it was his idea that he could shapeshift. And that we’re living in a world that has dragons. And… and I was a maiden that had a tavern and there would be knights who came by to slay the dragons but the dragons are actually our friends… It’s like reading a book but you’re in it, you know? And he doesn’t ask about who I like and what I like and what I think is cute all the time. That’s so annoying.”

“You like hanging out with Tenma?”

“He’s okay,” you offer and she snorts. “If he ever gets on your nerves, you can tell me, okay? I know boys can be annoying too.”

“I can handle Tenma,” you tell her, knowing you’re right. “But can you, like, not allow me to go to Ryo’s sleepover next week? She’s so obsessed with boys and she always pranks someone during sleepover. I don’t want to wake up with my head shaved.”

“Do you wanna be my girlfriend?”

To say you’re surprised would be an understatement.

It’s not that you don’t get chocolates and confessions, because you do, a lot actually even though you decline every time, but never from Tenma.

For a long second neither of you does or says anything and all you see of him is the back of his neck as he bows.

But then he pops up, a weird grin on his face.

“Got you!” He declares, opening the pack of chocolates and biting into it without a moment of hesitation. “Did you think that was real?”

“No,” you say even though that’s a lie, “Why did you do it?”

He shrugs, offering you the chocolate. You take a bite as well, feeling a little smug that neither of you cares that it will be an “indirect kiss” as the girls call it.

“Everyone thinks we’re dating,” he admits finally when he pulls the chocolate back again, “just wanted to see what you think about it.”

“It’s annoying,” you declare ad you should have watched his face a little closer because something like a shadow moves over it, but it’s gone before you can catch it. “You’re like my brother.”

“Yeah,” he says, but it sounds a little weak for someone as headstrong as Tenma.

You don’t wanna think about it though, so you poke his shoulder. “Where did you get the chocolate?”

“Someone confessed to me. I said no but I kept the chocolate because they thought I was dating you and still confessed. That’s stupid.”

“Mhm,” you don’t ask for a name. “Wanna stay and play a bit before we walk home?”

“Volleyball?” He asks, ears perking up.

“Sure.”

- 14 -

Neither of you is dating anyone.

None of your girlfriends believes that you’re not into Tenma and you’ve given up on convincing them of the truth. You don’t really want to date anyone. You like solving puzzles and coming up with crazy ideas that Tenma can bend and fold into even crazier stories. You like going for a run with him in the morning because even though you hate waking up early it sets your mind at ease and you like going for a run with him in the evening because without it, you’ll be unable to sleep.

Sure, there are some good-looking boys in your class. But maybe you’ve spent too much time around Tenma, or boys in general, to find any appeal in them.

They fart and they burp and they dig their dirty fingers into their noses and they refuse to shower even though they smell awful and sweaty. The number of times you’ve had to drag Tenma into the shower, turn it on, and hold him under the spray because you couldn’t allow him in your room otherwise and he wouldn’t go on his own is too high to admit at this point.

It helps a little that Tenma thinks the same of girls.

Not that the girls from your class are as disgusting as the boys.

But they giggle too much and they always flutter their lashes at him which he thinks is a little creepy and they don’t listen to him when he talks about anything that isn’t their appearance.

“I like talking to you instead,” he admits and this is probably the highest praise he’s ever sung you, “you know what I’m talking about.”

And you know what he means because you always know what he means. It’s not that hard. Tenma likes stories, the crazier the better, and he likes volleyball. And food, but he’s picky with that, giving you his tomatoes and eating all your salmon even though you’d have wanted to eat that yourself.

All the other girls in your class are talking about boyfriends and getting married and having a family and all you want to think about is solving riddles with Tenma or telling him a story so he doesn’t make you practice receives with him.

- 16 -

“Did you get your first kiss already?” Hisoka asks and you shake your head. Nothing sounds less appealing than tasting someone else’s spit.

“Don’t you and Tenma kiss?” She asks and you stare at her as if she’d said that Alien’s are real.

“Why would we kiss?”

“You’re dating, aren’t you? Everyone says that you’re dating.”

“He’s like my brother,” you tell her. “We grew up together.”

“But you’re the manager of the Volleyball team too.”

“Yeah, because I like Volleyball.”

She huffs. “Okay, who do you like? I think Tsukishima is still single.”

Tsukishima, blond, tall, and universally liked, blushes like a strawberry. You glare at him for eavesdropping.

“I’m not interested in anyone,” you declare loudly. You hope that’s the end of it.

It isn’t.

“Hey, can you walk home without me? We’re going to prank the store owner down the street,” Tenma hands you his bag without waiting for an answer.

You walk home alone, grumbling to yourself about how you would have wanted to play along with the prank.

But it doesn’t matter.

After years of being an okay player, Karasuno’s trainer seems to have spotted something in Tenma that he didn’t even expect there himself.

Extra training. More time on the court. Recognition from others.

Soon enough you’re sidelined with Tsukishima and the others.

First-year managers are not allowed on the court during official matches.

Is there anything worse than realizing that you’ve made a mistake? Putting all your faith in one friend only to realize they can drop you without a moment’s hesitation?

“Tenma’s here,” your mother calls out from the kitchen.

You’re not fast enough at sprinting toward your door. He slips into your room before you’ve managed to close it.

“Tsukishima told me you’re leaving the team?” He sounds out of breath. Did he run here?

“I’m just a manager, it’s not like the team will notice,” you scoff, pushing him off your bed. “Besides I’m taking up Advanced English, so I’ll have more time to study.”

“What? Are you going to turn boring now?”

“You’re boring!” You scream, surprised by the anger that’s spilling from your lips. It feels as if he’d stabbed you with that question and all the words are just the blood that’s spraying out of open wounds. “All you do is play volleyball and think you’re the greatest and it sucks!”

“You suck!” He yells back. “You’re just jealous I’m finally cool!”

“You’ll never be cool!”

Tenma stomps his foot like a little kid before storming out of your room.

You can hear the front door slam shut all the way up to your room and if you crawl into your bed to cry right after that’s nobody’s business but yours.

And your mother’s, as it seems, because she appears at your doorstep just a few minutes later.

“Wanna tell me what that was all about?”

“No.”

“Hm, maybe not right now,” she offers at your tear-soaked voice, “but I expect an explanation until tomorrow evening, okay? Tenma’s family to me too. You know we can solve all fights with good communication.”

You don’t answer and she leaves you alone to wallow in your despair.

“Tenma wants to apologize,” Udai-san pushes him toward you. Your mother nudges you forward in much the same way.

“I don’t want you to be cool,” you say instead, the words prickly on your tongue. “I like you better when you’re not cool.”

Tenma’s eyes flutter around the room, arms crossed. Your mothers leave the room and you sink into the floor, annoyed and hurt and so many more things you can’t properly name.

“Do you really think I’m boring?” Your voice is much to vulnerable for your liking.

But it stills his nervous movement and he sinks onto the floor just like you, heavy and exhausted. You’ve never fought like this before.

“I think you’re trying to be,” he offers quietly, “but I want to you to keep playing Volleyball with me.”

“I’m just a manager.”

“Yeah, but it feels like you’re playing with me. And… and you’ve always been the smart one, okay? Everyone’s always said: Tenma, you should be more like her. She’s so smart. Can’t she tutor you? No one ever told you to play Volleyball like me. No one ever told anyone to try to be like me until now.”

“I’ve always wanted to be as creative as you,” you offer and even though he wrinkles his nose you can tell he’s touched by that.

It feels like you’re standing at a crossroads. Whatever you decide or do or say next will change the trajectory of this friendship. You’re not ready for that. You doubt you’ll ever be.

As long as there’s the safety of your past, you’ll always try to grasp it.

“Do you wanna play my dog?”

- 18 -

You’re not sure if it’s the awful music, the crowd around you, the smell of sweat and food and spilled soda, or just everything all at once, but you don’t think College parties are for you.

You recall a balcony or backdoor to your left so you move that way, push against the wall of bodies with everything that you’ve got, panic already bubbling in your throat.

Someone grabs your hand just as you’re gasping for air and with a well-aimed push you’re through, cool air hugging you like a loved relative at a family dinner.

“You good?” Tenma’s squinting down at you. He’s grown a little during break, though you doubt he’ll ever be as tall as the other guys on his former Volleyball team.

“Yeah, thanks.”

His hand is still around yours, now pulling you down the path into the dark garden.

“Where are we going?”

“Dunno, getting some fresh air into you. Met anyone you like?”

“Yeah, the fridge.”

He snickers. “What about that girl from your business Class?”

“She’s trying to eat the face of some guy I don’t know.”

“Tsukishima?”

“Pretended he didn’t know me.”

“Aww, I’m wounded.”

“I bet you are. What about you? Any hot girls tried to talk to you?”

“About that,” he knocks his elbow into your side, “one of them tried to kiss me.”

“A hot girl tried to kiss you?” He nudges you again at your incredulous tone.

“Don’t act so surprised. I’m famous.”

“Bet you are,” you snicker. “But what happened? Did she realize you’re not a tall girl but a small guy and run away?”

“No,” his voice sounds weird now, but you can barely see his face in the dark, “I turned her down. Didn’t want my first kiss to happen at some party.”

“How do you want your first kiss to happen?”

“Ah,” you know he’s just shaking his head from left to right as he’s thinking, you don’t have to be able to see him for that, “Like this, you know? In the garden in the dark? That’s kinda romantic.”

“Should have brought someone else over here then.”

His hand lets go of yours.

“Right,” he says, voice weirdly tight.

“Shit, did I ruin the mood?” You ask, nudging your elbow into whatever you can reach, “I can get that hot girl for you. Just tell me what she looks like.”

“Do you wanna get KFC instead?” He must have turned his back to you. You don’t know what you said to derail this conversation, but it’s clear he doesn’t want to keep it up.

“Sure,” you agree, “but you’re paying.”

- 20 -

Tenma has started growing his hair out.

You’d be lying if you said it didn’t suit him.

You’d be a filthy, awful, terrible liar if you said you didn’t want to drag your hands through it all the damn time.

“You should cut your hair,” you tell him when you meet up for lunch, “You look like a homeless guy.”

“And you look like a sexy secretary,” he jokes, pulling you in and putting you in a headlock. It feels brotherly and it’s just what you need to get through this lunchdate that’s not a date.

Somewhere in between graduating Highschool and today Tenma’s gotten hot.

Or maybe you’ve just finally gone through puberty, discovered all the hormone’s healthy teenage girls were supposed to have.

Last week you even sniffed his leather jacket when he was in the bathroom and you wished you could have put in on for a few minutes, but you feared he’d notice and how would you ever live that down?

“Did you get any feedback on that story you submitted?” You ask, trying not to overthink his comment. It’s probably meant as a loving insult, after all you’re not a secretary.

“Yes, actually, they told me they’re printing it.”

“No way,” you shut the menu again, “You’re joking, right?”

He grins. “You think I’m joking?”

“Not really, but I wanna make sure you’re being honest with me before I pay for your lunch.”

“You could let me pay and we call this a date,” he says and even though you catch yourself freezing up you can see on his face that he caught it.

“I was joking,” he tells you and if you’d be able to be honest, if you’d trust yourself not to ruin this, you’d tell him that his joking is the one thing that makes you still freeze up in fear.

After all, you don’t throw away a friendship of twenty years to a joke, right?

“I know,” you tell him pointedly, clearing your throat and opening the menu again. “Which means you’re paying for yourself.”

“Come on,” he whines, but his voice comes easy now, which means you can breathe again.

The moment is gone and somehow, you’re sure, you’ll survive the next one too.

“Can’t your girlfriend sleep in your room?” You can’t place the voice for a moment even though it sounds familiar.

“Not my girlfriend.” That’s Tenma. Who are they talking about?

“Well, if you keep having a girl over make sure she has a place to sleep that is not the living room. I need my space in the morning.”

“Sure, sure.” Tenma sounds like he’s not taking this seriously.

You blink and wipe the drool from your face.

“Morning sleeping beauty,” Tenma’s face is so close now you can smell the toothpastey-freshness of his breath.

“What day is it?” You ask, feel your jaw crack as you yawn.

“Sunday,” he pulls you up with ease, “Let’s put some of my spare clothes on you before we meet up with our parents. Or did you bring something?”

You rub your eyes as you lean on him. He might have stopped playing Volleyball, but he hasn’t lost his muscles.

The memories are slowly coming back to you. Going through his newest idea, a Manga this time. Reminiscing over old footage from his Karasuno days. Sharing one, two, maybe three beers as you giggle and swat away his hands on the Couch.

You can only hope you didn’t say or do anything embarrassing last night.

But this is Tenma. He’d let you know right away if you had.

It gets easier to live with your crush.

Tenma never mentions any girl he’s seeing or points out who he thinks is cute.

He’s pretty good at keeping in contact even when he’s so lost in his creative mind that he forgets to eat.

And while your work is equally demanding, the hours there are more regular.

It’s not uncommon to find you in his kitchen after work, growing from putting ready-to-eat food onto plates to actually preparing home-cooked meals. They’re not awful and you think that’s the highest praise you can get.

Sometimes, when it’s so late you can forget about catching a train back home and Tenma’s so tired he sounds like he’s speaking a foreign language, you end up sleeping in the same bed.

If you drag your fingertips through his hair then, hear him mumbling softly under his breath as you fall asleep, that’s your secret to keep.

- 22 -

Tenma’s a full-fledged Manga Artist now.

You got your own promotion just a short month later and as he raises another glass on your good work, the question tumbles out of you before you can stop yourself.

“Do you want to move in together?”

His grip is suddenly too tight around his glass. You can tell because you’ve grown a bit too observant lately, always way too laser-focused on where he is and what he’s doing and how he’s smelling like, freshly-showered or cozily slept-in.

“You can say if it’s a stupid idea,” you ramble on, “I mean, I’m over at your place all the time anyway to make sure you’re eating enough. It would be weird though if one of us brought home a date, but like-”

“Sure,” Tenma clears his throat, “we could move in together.”

He deflects all further questions though, whether it should be closer to his work or closer to yours, how many rooms you’ll need, and if you’ll be able to get a cat, instead filling up your glass again and again.

Eventually, you walk home arm in arm, each of you trying to support the other.

It’s a hopeless case but that doesn’t mean you’ll stop trying.

“This was fun,” you say at the train station, debating if you’ll take the train home or find some excuse to stay at his place.

You turn your head, surprised to find him this close. His eyes are wide open, dark and beautiful. He’s always had the prettiest eyes.

You’re still debating their color - more of a dark brown or maybe black - when he leans further in.

You half expect him to headbutt you when instead, his lips touch yours.

The kiss is so soft, you think you’re imagining it, along with the sigh that follows it.

But you’ve always been a realist, digging your fingernails into the skin of your arm to prove yourself you’re not dreaming. It hurts.

“Tenma?” You ask, breathless and floating, “Did you mean to do that?”

His face turns pale, eyes wide like those times you’ve pushed him into a cold shower to sober him up.

“SHIT!” He pulls away so quickly that you stumble, lose your balance and fall flat onto your ass.

“Shit, shit, shit!” Tenma’s rubbing his face with his hands, up and down, up and down, and you’re left sitting there, backbone hurting, the world spinning in the wrong direction.

“Okay, shit, this…” He’s folding himself into a tiny version of himself, just across from you on the cold sidewalk, “I didn’t meant to do this, okay? I know you think of me as your brother, so we can just pretend this never happened, okay? I’m drunk. You’re drunk. We’re going to have forgotten about this tomorrow-”

“Tenma?” You interrupt him, your voice weirdly cloud-like. “Are you in love with me?”

He deflates like a balloon, there’s even a little whistling sound coming out of his mouth when he further shrinks into himself.

“Maybe?” He squeaks out. “It doesn’t have to mean anything, though-”

“I love you too.”

There. You’ve said it. You can’t take it back. Maybe you’ve misunderstood a lot of things tonight, you’ll for sure be able to blame the alcohol for it, but you don’t kiss people you don’t like, right? Especially not if you waited twenty-two years for that.

Wait, did Tenma even wait that long? Is this even his first kiss like it’s yours?

“Why didn’t you say something?”

You blink, shaken out of your musings by the petulance in his voice.

“You didn’t ask.”

- 24 -

You’re not sure what wakes you, but his side of the bed is empty and cold.

You push yourself up with a groan, hiss when your feet touch the freezing ground.

You don’t have to look long to find him, hair disheveled, eyes foggy.

“Hey,” you wrap your arms around his shoulders and rest your chin on top of his head, “I miss you.”

“Sorry,” he yawns, “I’ll be in bed in a minute.”

“You said that four hours ago,” you remind him, leaning further into him, “can you still see what you’re drawing?”

“If I lose this idea-” he starts before a loud, jaw-cracking yawn cuts through his sentence.

You unwrap yourself to dig your thumbs into his shoulders, press a well-aimed kiss underneath his left ear.

“Come to bed,” you're not surprised when he follows you without another argument.

Last week one of your coworkers mentioned off-handedly that your boyfriend looks like a delinquent, all long hair and dark shadows, the hint of a stubble and a shirt he forgot to iron.

You weren’t meant to hear it, you’re sure, but you don’t care anyway.

He curls around you now, long limbs and warm hands, head resting heavy on your chest.

You drag your fingers through his hair, up and down and up and down, tell him about all the plans you have until you fall asleep along-side him.

“Look at you,” Saeko pulls you into a hug, “You’re practically glowing.”

You snort. “Don’t tell that to my mom. She’s started asking about grandchildren.”

“Yours too?” Akiteru jokes, turning from you to Tenma. “Are your parents united on the grandchildren front or are they more like ours?”

“No, no,” Tenma shakes his head, “My mom is just as insistent that we get started. Our mom’s are best friends for a reason.”

“And they never tried to set you up?” Saeko waves at someone across the streat before dragging you onto the seat next to her, “I smell a story.”

“I’m not sure my mom really cared about it as long as we stayed friends,” you think back. “But there was that time when she asked me to stop taking baths with you.”

Tenma’s face turns pink.

“I remember that time well.” He laughs along with the others, but your hand finds his under the table, squeezes tight.

You like to think that he fell first but you fell harder, but he disagrees.

If anything, he likes to say, I love you most.

“I say,” Saeko interrupts your thoughts, slinging an arm around you, “we play it like your parents. We just have to have babies around the same time and the rest will be history.”

“Don’t get ideas,” Akiteru says but you know him, he’s just as helpless against Saeko’s charm as you are.

“Not the worst idea she’s had,” Tenma whispers into your ear.

- 26 -

“Morning Udai-San,” Akaashi greets you.

“I told you to call me by my first name,” you tell him, laughing when he blushes a soft pink. “How’s it going, anyway?”

“Good. We’re actually on schedule, but I don’t want to jinx it.”

“Hmm, I get it.” You resist the urge to tousle his hair. “Is Tenma in his office?”

“Yes, I was just going to get coffee. You want some as well?”

“No, but thanks for asking. What are you getting for Tenma?”

“Two shots of espresso and extra sugar.”

“Make it one shot and I’ll make sure you get a promotion,” you wink and he winks back, slipping out of the office.

“Baby?” You ask, slipping through the door.

Tenma’s leaning heavily onto his desk, one hand playing with his hair as he thinks.

“Hmm?” He sits up, opens his arms to welcome you. “Hey, what brings you here?”

“I left Naoki with Saeko and Mi, they were playing so nicely.”

He smiles as you plant yourself on his lap, sink into him like you’re not much bigger than your toddler and not the grown woman you are.

“You good?” Tenma asks, rubbing a hand over your back. “You seem in your head today.”

“Yeah, I am, I just…” You sigh and turn your head to kiss his cheek. “I’m glad you stayed my friend.”

“Where’s that coming from?”

“I was thinking about how I don’t have that much patience. I don’t know if I’d kept crushing on you for as long as you kept crushing on me. What if you’d have given up? We wouldn’t have gotten together.”

He hooks his head over yours, wraps his arms a little more snuggly around you.

“Listen, I didn’t stay your friend because I was hoping you’d one day see me as more. I stayed your friend because I’d rather have you as my friend than nothing at all. After all you’re the best friend I ever had.”

“Even though I made you play my husband, my dog and my dragon?”

“Especially because of that.”

“Did you have fun playing with Mi?” Tenma asks your thirteen-month-old.

The bathroom door is open and you can hear them splash around in the bathtub.

“Mi,” Naoki repeats with excitement.

“Yep, Mi. Now, can you say Dada too?”

“Mama.”

Tenma laughs, easy and carefree and you leave the dishes in the sink in favor of joining him.

After all, the dishes won��t run away, but those little moments with your family might.
