When you were younger, stupider and shameless, you and your only friend Shoto, would play detective during your free time together. At the age of five, you and your comrade had already solved ONE case, the infamous 'who stole older brother's motorbike?!' case, which you and shoto apparently 'took credit for' or whatever that means. Despite how much you swore to your brother how you and Shoto knew where it was before the police. And how you tipped the cops off with your super secret telepathy quirk that no one but shoto knew about.

He responded with a, "well if you're so smart why don't you figure out where my old 3DS is?? by the way, you don't have telepathic powers, forehead." You'd clench your fist every time that cursed nickname left his lips, but anyways, you accepted his challenge, walking away cursing him with the most vulgar name you could think up, telepathically of course. you swear you heard his breath stifle in shock as you stomped off, coincidence? I think not.

Your winning streak of problem solving ended with anger at your rivals, the police down the road, when they refused to let you into the station after you relentlessly demanded that they let you see the files of fifty year-old unsolved homicide case. The next day you sulked to Shoto during lunch, who stared at you with that blank stare he always does."you tried to break in again?" An accusation?!?!?!? The tipping point.

You fake-angry threw your paper cut-out detective badge, that you and your best-friend made during arts and crafts, with all your strength, only for it to slowly flutter to the ground awkwardly. That day you announced your retirement from the force. Claiming all the hard thinking was giving you wrinkles, that only caused shoto to look more confused, tilting his head to the side. "Wrinkles?"

"On my forehead." You huffed.

Your interest for the antics of detectives on tv and corny live-action crime thrillers died off as your ambition and hope to become a real life pro hero ignited, as did your connection with Shoto, even if you started to see him less frequently as the years of your childhood passed by. It was a blessing that you managed to land a place in class 1-A alongside your companion. Your bond reinvigorated, grew stronger as you were reunited with the boy, the lingering figure of his father, Endeavour had dissipated, granting the boy a newfound freedom. You found yourself spending almost all your free time with him now, way more than you ever did when you were kids. And you were grateful for it. So very grateful.

Now, both you and him had matured, albeit not a lot since you were both fifteen, but in a fifteen year olds eyes, it was a lot. The boy's once chubby cheeks now had a more slim-chiseled appearence. His head of hair was the same length, perfectly split down the middle, not one stray hair misplaced on either side. His eyes were more narrowed and stern, still fronting that blank look that his eyes always held. However hard his stare was when he looked at others, he'd never dare look at you with that coldness, whenever he caught himself glancing at you his creased brow would almost immediately flatten. His gaze defrosted into liquid, a softness so delicate and reminiscent of the early days of your relationship. The days where he'd follow you around, craving the warmth of your presence, your smile, you, and everything a five year old brat could offer. In your case, it was friendship.

You and him were two peas in a pod, Detective Shoto and his partner, Sometimes in class you'd daydream about playing detective with him, like how you used to, but you guess you both were a little too old for that now. Besides it's not like there was any mysteries to be solved in the halls of Yuuei.

Not until today.

"a love letter!?!? oh wow!" Deku shrieked a bit too loud for your liking. His whole body shook as he held onto the straps of his backpack. A few students lingering around the halls looked towards the commotion.

"Yeah but shhh!" You leaned closer to the boy pressing your finger to your lips harder and harder. " I don't want anyone to know, it's embarrassinggg! What if they're messing with me? I don't even know who wrote it! I don't wanna get my hopes up you know..." You mumbled that last part, your finger silencing yourself made it hard to talk. You've never been popular with the male species, only ever receiving confessions as jokes from more popular, less disliked, boys. Not that you minded all that, you had a best friend after all, and he was a boy! You were considered popular and you were liked by him!

You tossed your head about to shake the thought of Shoto to no avail. You felt you cheeks heat up. "Can you read it out to me? Maybe they gave a clue as to who they are!" Deku ignored the redness in your face, chalking it up to nervousness. Yeah, you were nervous alright, nervous about what Shoto would think. He's always been relentless in the pursuit of your attention, you couldn't help but wonder how he would react to all this. Would he be mad? No why would he. He has no reason for all that.

You take your time reading out the letter you found in your locker, looking up to meet Izuku's eyes after every sentence, waiting to see if he caught on to any hidden meanings written in-between the lines of the confession. You'd read the letter countless times, scanning over every word to no avail. Only deciding to drag Deku into your conundrum as he was walking past. Whoever had written the letter gave no clue towards their identity. It was just a confession. No 'can you meet me behind the school later today?' or ' will you go out with me? Just an ordinary love letter. Apart from the last section. At the bottom of the paper read a slightly threatening, ominous quote:

"I'll set your heart alight. "

The words made your chest tighten, but not in a good way. It gave you a funny feeling in your stomach, such a normal letter ending so strongly, you were kind of unsettled. "Don't you think that last parts s'a little odd?" You mentioned after finishing up reading. "Kinda sounds like a threat to me." You suddenly gasp, "What if our undercover lover is a villain! They could be plotting to kidnap me ..or worse!" Due to recent events, everyone had the possibility of kidnapping looming over them.

" Umm.. I doubt that a villain could sneak into Yuuei, especially now. I think it was maybe just an attempt romance." Deku chuckles, trying to lighten the mood.

"No I seriously thi-

"Yn. Midoriya." Shoto Todoroki stood behind you. You hadn't even noticed him sneaking up on you, whether it was his intention or not, he scared you straight.

"Oh! Hi Shoto!" You calmed yourself, turning your head to make eye contact with him. He only grew closer to you, taking the eye contact as permission to get closer. You could feel the air get hotter as he lingered next to you, reaching his head forward so he could peek at what you were holding so tightly in your hands. His eyes offering no insight to his current emotion whatsoever.

"What is that?" Tilting his head. Suddenly embarrassed you smushed the paper into your chest, crinkling it. "Uhhh.. I got a letter! I don't know who it's from though. Not that it matters." You shrugged. Nice, the nonchalant approach.

"What kind of letter?" He strained his neck for a moment longer before backing up. Face still, ice cold. You sighed at his retreat. Anxiety welling up in your stomach, 'why the hell am I so paranoid for?' You thought.

You were about to dodge the question when Deku asnwered for you, "Its a love letter! From someone unknown, we're actually trying to figure out who it could be from!" At that you crumpled in defeat. Thanks a lot Izuku. Why the hell are you trying to cover it up so much anyways? Huh?!? Your inner monologue accused you.

"Oh." He stepped back even more, No longer feeling his warmth, the hall seemed a whole lot colder without him so close, you urged to scuttle up to him, Only to turn to see Shoto preparing to leave.

"Would you like to help us Sho?" You offered, not wanting him to go so soon. Leaning at the hip towards him, head tilted down, eyes looking up at him.

"No thank you. I have to go, Goodbye Yn, Midoriya, good luck." And at that he started to walk away. You rushed to find something to say, deciding to just let him go, offering a small, "Bye Sho." Along with Izuku's cheery goodbye. 'Was something wrong? Did I do something wrong?' Your spiralling thoughts were soon interrupted by Deku," I wonder what that was all about." The look on Izuku's face mirrored yours, laced with confusion, only less angsty than yours.

"he's probably just busy with assignments or something, wants to get ahead." You chirped, lightening the tension.

"weird of him to turn down an opportunity like this though, he's usually all over this kinda stuff, he's a real hardcore theorist sometimes!... don't tell him I said that."

"oh really?" you jest. Tension dissolved, nice. As if you and him weren't attempting to solve murder mysteries during break time a couple years ago. The memory returning to you, you can't help but feel a little sad.

A couple moments of silence and then, "Ive got it! we could track them down through their handwriting!"

"yeaahhh... but the letters printed!" you retired the letter from your iron grip with an obnoxious groan, provoking a handful of glances from students passing by. "good idea though." You shrink into yourself a little, eye twitchy as you try to disappear through sheer willpower.

"the culprit has thought this out really well.."

"Yeah.. no clues or anything. Apart from the curse at the end."

"Yeah."
