Aizawa is definitely one of my favorite characters and I've always wanted to write about him! This piece is also set after the sports festival (after Aizawa is healed of course) :) Also the reader will be an adult...just throwing that out there lol. Enjoy!

You huffed and pulled at your black shirt as you scrutinized yourself in the mirror. You wondered if you looked professional or too corporate. You sighed and started to doubt yourself.

After a drastic career change you made after working at an unfulfilling office job for a long time, you had entered college again and decided to study education. You had pursued multiple internships for teachers at different schools. Your passion was teaching but you had yet to find a school that seemed exciting enough for you.

That was when, on a whim, you decided to apply for a one-semester internship at U.A. High School. You believed that they would turn you down instantly because of your lack of experience, but to your surprise, they called you back the next day. The principal set up your internship and mailed you your U.A. ID card.

You walked toward the train station quickly remembering what Principal Nezu had told you over the phone.

I will be your supervisor but you will be studying under Mr. Aizawa for the duration of the internship. He's a bit strict but also a bit sleepy so it won't be that bad! He's one of our best teachers.

As you stepped on the train, you wondered what he meant by sleepy. Did Aizawa sleep during class? Does that mean that all of the teachers at U.A. could do that?

You were still lost in your own head as you got off the train and walked towards U.A. High. You pulled you ID out of your pocket and walked under the huge front gate. You had arrived half an hour early before the school day started in order for you to meet Aizawa.

You climbed the steps toward a giant front glass door and walked in. Hmm, Principal Nezu said that Aizawa's class is homeroom 1-A, you thought to yourself as you wandered down hallway after hallway. You finally reached your destination and found yourself staring at another huge door.

Geez, this place is insanely built!

You knocked on the grand door and waited for Aizawa to answer. Instead, you were met with dead silence.

"Huh, well I guess I should just let myself in..." you said as you quietly opened the door. "H-hello? I'm Y/n L/n, I'm here for my inter--" you started to say before you were cut off midsentence by a loud groan.

Your eyes widened as a tall figure emerged from behind the podium that was in the front of the classroom. Your mouth dropped open when you realized that the figure was a tall man with long black hair, who was completely encased in a bright yellow sleeping bag.

"U-Uuh are you Mr. Aizawa?...B-because i-if you're not, I want you to know that I have a b-brown belt in karate!" you said to the strange man, a bit louder than you wanted to.

He unzipped his sleeping bag and stepped out of it carefully as he glared at you with dark tired eyes.

"Of course I'm Aizawa. I wouldn't be able to make it past the U.A. gate without an ID." he said calmly in a completely monotone voice. "You seem to lack reason and intuitiveness."

"OH my gosh, I'm so sorry Mr. Aizawa! I'm the new intern here for U.A. and I'm going to be working mostly with you Mr. Aizawa--"

"Just call me Aizawa."

"Oh ok, well I'm here now and my name is y/n l/n. It's a pleasure to be able to work with you at this incredible campus!" you said as you bowed slightly.

"Mmhmm...now that formalities are out of the way I'm going to go back to sleep," he said as he zipped up his sleeping bag again and flopped down on the floor behind the podium.

"But Aizawa, class starts in nearly ten minutes. We should greet the students and tell them who I am."

"I thought you were an intern, so stop telling me what to do and let me sleep," he said, drowsiness already creeping into his deep voice.

Well, this is going to be interesting...

...

Three weeks later

You and Aizawa had developed a routine. You stayed out of his way and worked hard when he slept, and he was tolerant towards you. To you, the routine seemed a bit one-sided, but it was working so far.

Today you and Aizawa were staying a bit late to help Present Mic on grading some essays. Present Mic had to go on patrol that night so you two had volunteered to help him. You were both sitting in the teacher offices with the light dimmed slightly. Aizawa was a faster grader than you, but the dimmed lights and the quiet atmosphere were making you nod off slowly.

Aizawa looked up from his stack of papers and smirked at you.

"You doing alright y/n?" he asked you politely, albeit a bit coldly.

"Yeah...it's just that there are so many papers! Does Present Mic wait 'till the last minute or what?" you asked in frustration as you roughly wrote corrections in the margins of the essay you were grading.

To your surprise, Aizawa got up and went to the mini fridge that was near the door. He walked back and handed you a cold bottle of water.

"Here, it's all they had in the fridge," he said briskly. You thanked him and took the drink gratefully. As you took it, your fingers brushed his slightly and your breath hitched quietly.

He smirked at you again, obviously hearing your reaction. You cleared your throat awkwardly and hunched over your papers quickly to avoid eye contact.

Aizawa leaned closer to you as you continued to avoid looking him in the eyes. He huffed and leaned even closer until you could feel his hot breath on your cheek.

"You're acting weird, is everything ok?" he asked, actual concern in his raspy voice.

If you were being honest with yourself, everything was not ok. Lately, Aizawa had been creeping into your everyday thoughts more and more. You worried for his safety, you physically felt different around him, and you had finally realized that beneath that cold exterior there was a kind and selfless man that you may have been falling in love with.

I'm falling in love with you!

"I'm fine Aizawa, I'm just...tired," you said finally meeting his jet black eyes. His shook his head, obviously not believing you, and started to turn away.

Damn it! What do you have to lose y/n?!

You snatched his hand and turned his face towards you. His stubble tickled your hand as you gently pressed your lips against his. He tensed for a moment before melting into the kiss and relaxing.

You broke the kiss for a second before he cupped your face in his rough hands as he kissed you with more vigor this time.

His teeth slightly grazed over your bottom lip and you gasped in surprise. Your hands clutched his long hair as he devoured your mouth passionately.

His passion definitely took you by surprise considering how mellow he was with almost all activities. Not that you were complaining though.

He broke from the kiss to take a breath and you chuckled quietly to yourself.

"You don't know how long I've wanted to do that...Shouta," you admitted to him as he looked at you seriously.

"Trust me, you don't know how long I've wanted to do that either...y/n," he said his nose slightly bumping yours as he talked and gazed at you.

Needless to say, the grading did not get done that night.
