'Mine' Yandere!Shouta Aizawa X Reader

Shouta Aizawa was typically good at hiding his thoughts and feelings from those around him, keeping his actual personality at bay and hidden from others. But at certain times it became harder than usual to suppress certain emotions, especially when he began to get closer to you. Generally he could be labeled as a sadist, or a yandere, the former being known more, due to how he would sometimes take down larger villains attacking the city.

But the latter wasn't known to anyone, he tried to keep his possessiveness to a minimum, which was easy until he started to develop feelings for you. You made everything so much more difficult. You had started working at UA a couple of months ago and were introduced to him through Present Mic. He was constantly thinking of you, it was actually keeping him up even later than usual, and causing him to be even more aggressive with the villains he dealt with.

All he wanted to do was slam you against the wall and show you how you made him feel. But he needed to remain calm, for now at least.

"Aizawa I brought you a coffee, no cream or sugar, just how you like it." You said, placing the cup of coffee on his desk in the morning before classes started. "Thanks (y/l/n)." He mumbled from his yellow sleeping bag on the ground. He was trying to get at least a little bit more sleep before he had to get up and teach his class. "No problem. You know, you really should get more sleep at home. The floor doesn't seem like it would be that comfortable." You giggle, crouching down and moving some of his black hair out of his face.

"Mmm." Aizawa hums but doesn't say anything, "Well I better go get ready for class, I'll see you later." You say and stands up, "Meet me after school?" Aizawa finally speaks up, his black eyes follow you as you walk to the door, "Okay, I'll meet you here after the final bell. Later!" You grin and make your way to your own classroom. Aizawa sighed, he'll finally get to spend some much needed alone time with you like he's been wanting.

The school day went by rather slowly for Aizawa, today his class had a test and then some note taking, which meant it was a rather boring day for him filled with either silence or long explanations on quirks. He'd only managed to survive half of the day so far, making it to lunch where he walked into the teachers lounge, hands in his pocket and posture rather slumped. He stopped rather suddenly when he walked in though, lazy black eyes trailing from you to Present Mic in front of you.

Present Mic had his arm around you, he was pulling you in closer to his body and appeared to be whispering something in your ear which made you burst into a fit of giggles at whatever he said. Aizawa glared from across the room, debating on whether he should step in or not, he really didn't even like the idea of you with anyone else, let alone Present Mic of all people.

"Mic stop!" You giggled, playfully pushing on his chest and attempting to step away from him. Aizawa immediately stepped in after this, moving in the blink of an eye and pulling you away from Present Mic and towards him. "A-Aizawa?" You stuttered out as he held you to his chest, your face was glowing with a rosy blush now as you stared up into his black eyes. "Keep your hands off of her." Aizawa said, turning his gaze to Present Mic and continuing to glare at him.

"Wow Eraserhead! Chill man we were just chatting together. No need to get so jealous~" Mic teased, grabbing your hand and kissing the back of it. You glanced between the two boys, Aizawa seemed to be getting more annoyed with Present Mic after that. "Mic stop, I think you're making him mad." You mumbled, Mic pouted, "Alright, alright, I know when I'm not wanted. Shout if you need me though~" He grinned and left the teachers lounge.

Leaving you and Aizawa alone together.

"So what was all that about Aizawa?" You asked, looking up at him, he still hadn't removed his arms from around you, but you didn't mind. "I just don't like seeing you like that with other guys. Especially him." He huffed, arms slightly tightening around you but not enough to hurt you or anything. "So you are jealous?" You ask, (e/c) eyes wide in shock, Aizawa grumbled lightly in confirmation.

You giggled, reaching up and caressing his cheek, "You have nothing to worry about, I don't like Present Mic. Or any other guy for that matter. I actually like you Shouta." You smiled up at him. His usually pale complexion went crimson at your words all the way to his ears. "That's good because I like you too." Aizawa said lowly, walking forward and causing you to stumble backwards until your back hit the wall behind you. "Aizawa?" You asked, confused as to what he was doing.

"I've liked you for quite awhile, and there's something I've been wanting to do." He said, leaning down to your height and pressing his lips to yours in a gentle kiss that quickly turned passionate and steamy. When you broke apart you were both breathing quite heavily. "Wow." You mumbled, stunned at the kiss and his actions. "You're mine. And I don't want any other guy to even look at you." He said, gently nipping at your neck and leaving a mark there.

"Hopefully that will show them who you belong to. Now come on, we have class soon and my students are brats when they're unsupervised." He said, pulling away from you and gently taking your hand. Walking you to your classroom he gave Mic a dark smirk as you both passed him in the hallway, his smirk only growing when he saw Mic notice the mark on your neck and frown slightly. "She's mine." He mouthed before you both turned a corner.

He was rather possessive, and a little too much at times, but you didn't mind. After all, he kept things interesting and exciting.
