Probability: Teacher!Deku x Reader
“Teacher deku falling for another teacher! Thank you I love you'r writing it's so cute” I love this request! I work as a teacher so this was a lot of fun for me to do, haha. I’m sorry it’s so late! I hope there’s enough romance in this one for you. I’m a little rusty, so go easy on me. Warnings: I did not proofread. It’s midnight and I have work tomorrow so I have nothing to say in my own defense. Might delete this later honestly but hey at least it exists. Also the formatting on this one is slightly stupid because Tumblr sucks.
You loved your job a lot. You had always liked kids, but you also knew from a pretty young age that you wanted to be a hero. Being able to do both was your dream, something you had never even known to hope for until Principal Nezo had shown up at the tail end of one of your missions, a knowing smile on his face parallel to the confused wrinkle of your sweat smudged brow.
“I’d like to offer you a job.”
7 words that had changed your life. You guessed 7 was a lucky number after all. Then again, maybe luck had nothing to do with it. Most things came down to probability.
“So, class, who can tell me which is better? Relying more on your powers or relying more on your individual skills?”
Several hands shot up. You had anticipated this. From the beginning of the year, you had noticed your students took very different approaches to their powers and there was a hot debate about whose approach would lead to them being “the best”, Japan’s #1 hero.
“Kori, what do you think?” You point out the young girl, her hair as white as the ice her powers produced.
“Relying on your powers will give you the edge you need to defeat the enemy. They’re what give us that individual edge. Without our quirks we wouldn’t be heroes at all.”
You couldn’t help the small smirk that crossed your face.
“Well, there’s one more person I’d like to ask. Deku?” You looked up at the man standing in your doorway. “What do you think?”
For being the number one hero in the country, Midoriya could be terribly shy when put in the spotlight. He blushed from the bottom of his neck to the roots of his deep green hair. He had probably hoped to go unseen until the end of the class when you two traded places and he gave instruction while you observed.
You were still on probation and one of the conditions of being a new hire at U.A. with no prior teaching experience was that one of the senior faculty had to sponsor you. Midoriya had been kind enough to volunteer, so you observed his classes when you weren’t teaching your own. Right now though, an outsider could have mistaken your roles for being reversed with the way Midoriya looked like he was training to manifest an invisibility quirk.
“Well, uh…” He recovered quickly, flashing a huge smile. “The thing is, neither is more important. If you forget about one or the other, you’re bound to fail sooner or later. Some villains will have quirks that give them an advantage over ours, which is when it’s important to have a strong sense of your individual skills and power outside of your quirk, things like using your environment to your favor and being skilled at physical combat. However, our quirks can give us a powerful advantage when used correctly, and it’s very difficult to fight villains with powerful quirks using raw human skill alone.”
“Very good, Deku. I couldn’t have said it better myself.” You glanced up at the clock, seeing you were nearly out of time. “Alright class. Your homework this week is to write me a paper about the advantages of quirk-based fighting styles versus quirkless fighting styles and report back to me. Also, keep an eye out for trick questions. I might give you a pass, but Aizawa will not. Now get out of here!”
Your students quickly started packing their things, getting ready to head back to the dorms or to their next class. You were almost done for the day. Midoriya had one more class to teach and then you were off the hook. You were thinking about going out tonight, a reward for the long week you had been through. Fridays always sucked a little bit. The student’s attention span was never as good as you wanted it to be.
You cleared your desk off quickly, making space for Midoriya to take over. You shuffled your pens into the cup at the edge of the desk, snatching the slim black water bottle off the corner before heading for the back of the classroom. Sometimes you sat closer to the front so you could see what Midoriya was doing better but you knew today was one of his lecture days, meaning all you had to do was listen. You loved lecture days because it meant you could get a little lazy. Technically no one could prove you weren’t listening and if you hadn’t had enough coffee, well…there were no guarantees.
Midoriya stopped you on your way back though, a warm, broad hand coming to rest lightly on your shoulder. You had always liked the way he touched you, unobtrusive, gentle and kind.
“So…” he started. “Today’s the big day.”
You nodded, excitement filling you at the reminder.
“How do you feel about your probation period finally being over?” he asked.
“Honestly?” you asked. “I’m torn. It’s going to be awesome being able to run my classes independently, but I think I’ll miss getting to observe your classes and have your guidance.”
Midoriya averted his gaze, teeth grazing his lower lip. “Well, about that…”
“What?” you asked, alarmed. “Is something wrong? Was I supposed to continue my observations? I didn’t get enough hours, did I? I knew it.”
“No! No, that’s not it at all,” he reassured you. “I was just thinking it might be nice if we didn’t have to stop spending time with each other.”
“What do you mean?”
“Well, I was thinking now that I’m no longer going to be your mentor it wouldn’t be completely inappropriate of me to uh…ask you out?” He stammered through the words, ever awkward.
You were taken aback by the proposal. You had always harbored a secret crush on the hunky pro-hero, but he was so quiet you never would have though that he had returned the feelings. Despite you drooling over him every class he had never made any advances. You had sort of given up on him halfway through the year, assuming he would never see you that way.
Your heart fluttered in your chest, long-held crush reigniting.
“Um, I would, I would like that, if, I mean, if you would like that, of course, because obviously I care about what you like and if you would like that, also,” you stammered.
Damn. You sounded even more awkward than he did.
You were rewarded with a smile anyway, Midoriya’s whole face lighting up at your response.
“I would like that very much! Should we go this weekend? I know a good place we could to Saturday. You know, if would like that also,” he teased.
“I would in fact like that also,” you said, regaining your confidence.
“Good. I’ll pick you up?”
“Sounds like a plan.”
“What are the odds I would get to mentor someone as wonderful as you?” he asked, smiling softly down at you.
“The probability seems pretty good, actually.”
