The Onyx Desire Of An Onyx Heart [Aizawa x Student! Reader]

1: Cocksucker Blues

Hello! To clarify some things, this book is going to be a slowburn, meaning it'll take some time before anything super steamy happens. Reader is also in her third year. The chapters will be kinda short, at least 1000 words each, but hopefully that makes them easier to get through. I decided to write this for fun and to practice writing drama and school life and other thing anyway. Thank you for choosing this book and please enjoy reading, and I apologize to those that do read in advance lmao

The morning came faster than he would've liked, his clock had hit 6:30 when he'd barely even closed his eyes.

Aizawa sighed as he closed the door to his apartment, twisting the knob with the key and yanking it back out. Something in the corner of his eye made him glance to the neighbor that appeared to be exiting as well, and the first thing he noticed was the sapphire blue T-Shirt over a pair of shorts. His neighbor carried something in their arms, like a uniform, and locked their own door.

He was pretty sure it was a woman, though he could only see her back from where he was standing. But what caught his eye was the large, capitalized white text in the back of her shirt.

'COCKSUCKER BLUES.'

Alrighty then. What kind of place was she going that would allow her to wear something like that? The woman turned around, brushing (h/c) strands out of her face, and Aizawa froze when he realized something.

"(L/n), is that you?" he stared, squinting with disbelief.

(Name) jumped in surprise, but looked back at him, curious (e/c) orbs widening with a cheerful grin. "Oh, Aizawa-Sensei!"

Now. . . You know this story's going to end, right?

"Don't you have school? I don't think dresscode policies will allow you to go in like that," Aizawa scanned her body, she was practically wearing pajamas. It was a still early.

"Ah-Yeah, I was gonna go to my parent's house and change! I accidentally left my uniform skirt there over the weekend," (Name) laughed sheepishly, scratching her face.

"Huh? Then what're you doing coming from here?" he asked, confused. "Wait, don't tell you had a one night-"

"N-No, of course not," (Name) insisted, waving her hands as her face exploded with shades of red. "I actually just moved here on my own. I wanted to practice independency, but I guess I'm already off to a poor start."

Aizawa hummed in response. It was still early, and she'd gone through the effort to make up for her mistake. He wouldn't call it a poor start. Though, she wasn't his student to lecture anymore, so he kept his mouth shut.

"I see. Take care then," he put his keys in his pockets and walked passed her, down the stairs into the parking lot. He was almost certain she'd said something along the lines of 'you too', though he wasn't sure.

(Name) (Last Name). She was enrolled in the third year support course, so obviously he wasn't her teacher, but she did seek advice from him from time to time in her first year. That was because some of her friends were in his class at the time, hence how they initially met. Though, they'd grown apart in the time since. Seeing her face in the morning came as a surprise, especially as a new neighbor.

"Make sure to complete the CYU in fifteen minutes. No talking. Look at anyone else's work and you'll get an immediate F," Aizawa lectured to his current first year class, setting up a timer.

Their simultaneous groan of exhaustion went ignored. "Start."

And so, he had fifteen minutes to spend time grading their previous assignments. It was still mostly the kids that goofed off, like Kaminari, Ashido, Sero, that were still having a hard time catching up to the class. Maybe he'd assign them more work or something. No, that might just add to it. He'd figure it out later.

"You look distracted," said his coworker after school as he was going through revisions in the lounge.

"I'm just trying to see how to help these idiots in my class," replied the tired male without looking at Yamada. People like him didn't care about anything as long as no one died, so their life went by cheerfully and almost carefree. But if his students kept this up, they just might die themselves from their overuse of barely existing brain power.

He got home earlier than usual, mulling over things like that without progress was a waste of time. He'd figure it out tomorrow.

His door just clicked open when he heard footsteps behind him.

"Ah, Aizawa-Sensei! Good evening," beamed (Name), jogging over to him. Or to her door, he wasn't sure.

"Evening," he acknowledged. He was about to enter, until (Name) spoke out.

"Oh-Are you only eating that?" she asked with a sad pout, gesturing to what he had in his hands.

The 'that' she referred to was a bag of Chinese food, which he'd quickly gotten on his way from work. She said it like it was a bad thing, but he was being more generous today than just having instant noodles or something.

"Uh, yeah," he nodded, feeling awkward. Was he supposed to share or something?

"I can make you something else than just takeout food," she suddenly offered, her face heating up a bit. "I mean, I'm a decent cook. I just don't think it'd be good for your health if you keep eating things like that. Not-Not to be, um, rude or anything."

Did she have a crush on him or something? (Name) wasn't usually so shy, her hands were fidgeting with her sleeves as she avoided making eye contact.

Well, Aizawa wasn't particularly attractive or social, or all that likable. He'd gotten negative responses to his usually strict methods of teaching before, so he wasn't all that popular either. He brushed off the idea as her just being shy about talking to him like this instead.

"No, I get what you're saying," he said, then paused for a moment to think. "But it's fine. Thanks for the offer though, (Last Name)."

With that polite decline, he stepped into his apartment and closed the door behind him, missing the flash of hurt on her face before he did.

It wasn't like he doubted her skills, he'd seen her bring bentos to her friends in his class before. But he'd rather not get in trouble for having a schoolgirl at his place, or doing favors like that for him.

Something about it, despite how innocent the intentions were, felt inappropriate. He spent the night coming up with 1-A's next assignment and potential solutions for his failing students.
