today marks the one-month anniversary of your relationship with sonny brisko.

you still can’t quite believe it, to be honest. to think the two of you started off as the bitterest of enemies through the entirety of grade school (he ate the ant you helped cross the road! how dare! you overcame your fear of insects for that!), then desk-mates and grudging friends as you went through middle school, and by the time the two of you reached high school, you could no longer deny that he was your best friend.

even if he ate ants.

at some point in time, you developed feelings for him. 

it was terrifying, trying to straddle the line between ‘just friends’ and ‘hey i’m trying to test whether you feel the same, goddammit’.

things became even harder when he asked you to run in the student council with him, him as president and you as vice president. you spent hours and hours together, coming up with ideas, planning, rehearsing, convincing. 

you fell more and more for him as you watched him grow out of his shell, becoming a leader people would look up to and admire. he was better at leading the crowd than you were, although you were better at one to one conversations with people than he was. people found him intimidating to talk to individually, but your persuasive words and gentle demeanor swayed them onto your side.

against all odds, the two of you won, solidifying your positions. 

to celebrate, he invited you to an arcade to play games with him after school. just you and him, in an old-school arcade, with nobody else but the old guy manning the store and the weirdo playing pac-man a few meters away.

he watched you kick his ass and beat his high score in a shooting game, and told you without hesitation: hey, y/n. i like you. i’m pretty sure you like me too. so can we call this a first date?

at the time, you’d been too stunned to do anything but agree.

one tentative date turned into two, turned into you and sonny secretly holding hands under the table during student council meetings, sharing quick kisses in between classes. 

every now and then, you catch him staring at you intently. when you tease him about it, he flushes, looking away with a i can’t help it, y/n. you’re so cute. and cool. i like you.

that gets both of you flustered, giggling to clear the air.

the past few days, you’ve seen him come into school with cuts on his face or bloody knuckles. it’s nothing new, technically, you’ve seen him with bruised fists before, but it worries you.

he tells you it’s nothing. he’s a boxer, he just trained a little too hard and didn’t realize he hurt himself. 

you bandage up his wounds. “silly sonny, take better care of yourself, yeah?”

he grins, slightly crooked. “i mean, if you’re going to kiss me better every time, i might actually get hurt more.”

you boop him in the nose. “next time you get hurt, i’m not going to kiss you. how about that?”

he pouts. “nyoooo!”

god, he’s cute.

jump forward a few days later, you’re discussing meeting plans with the school council secretary. “how about we discuss this further over lunch later? my treat, if you’re interested?”

you’re about to politely decline when the secretary flinches violently. “on second thought, um, i think it’ll be better if we continue this tomorrow. i’ll. um. talk to you later!”

he flees the meeting room.

you would say it’s strange, if you didn’t see sonny standing in the doorway with the most frightening glare on his face.

he wipes the frown off instantly once the secretary is gone, but his dark expression stays. you’re so stunned you don’t even notice him lock the door behind him.

he walks towards you slowly, purposefully. almost predatory.

your mouth opens and closes, but you can’t speak, like you’ve been muted by the overwhelmingly threatening aura sonny is exuding.

the dark look in his lilac eyes makes you feel like you’re being hunted.

before you know it, he has you backed into a corner. his fist slams into the wall next to your head. you don’t know when you started shaking, but here you are, trembling like a leaf, sonny towering over you.

“don’t talk to any guy but me anymore, okay? i only love you, and you must only look at me. you understand?”

he’s so close, you can’t look away even if you wanted to. “y- yes. sonny.”

he smirks, his free hand cupping your cheek and stealing a kiss that leaves you dazed and breathless. “good.”

sonny steps away, and it’s like all the energy from before had disappeared without a trace. “haha, sorry, y/n. i guess i’m just a little insecure. anyway, wanna go for lunch?”

“sonny brisko, what the fuck is up with you today? that was really scary!” is what you want to ask.

but what comes out instead is “sure! sushi and negi, right? i’m in the mood for some aburi engawa.”

OMAKE: A FEW HOURS BEFORE SONNY ASKED YOU OUT...

sonny stepped into the alleyway behind the school, hands in his pockets. two other boys were standing there, smoking and laughing to themselves. 

he greeted them with a smile. “so, i heard you were talking shit about my y/n.”

“oh fuck,” whispered one of the two boys, dropping his cigarette, “it’s the commander! shit, man, i’m sorry, i’m taking it all back! i said nothing about your crush!”

the other boy laughed disbelievingly. “why are you so scared? he’s just some pretty boy, right? i bet we could beat him up easy, it’s two against one. i don’t believe in that commander bullshit.”

he tried to walk past sonny, but sonny stepped into his path, blocking the exit. the angelic smile stayed on his face. “i didn’t say you could leave.”

the boy sneered. “who are you to order me around? maybe you’re the head of the student council but you aren’t the boss of me.”

“tsk.”

sonny sighed, his lips curling up in a savage, deranged grin. he rolled up his sleeves, clenching and unclenching his fists like he was warming up. “i’m meeting y/n in a bit, so i better make this quick.”

less than a minute later, sonny stepped back out of the alleyway, leaving two bruised, bloody and unconscious bodies behind him. he whistled merrily to himself as he cleaned the blood off his knuckles. he couldn’t let you find out about his little side hobby, could he?

you’re the light of his life, after all, and he’d like to keep things that way. 

even if he had to slaughter the rest of the world for you to belong to him forever.
