Eijirou never knew Aizawa had a daughter. But he had a girlfriend, why should've he cared? Sure the thing changes when you find your teacher next to your girlfriend after she asked you to meet her parents.

It should've been a simple nice dinner, obviously he accepted, after his mother, too, told him she'd kick his ass if he refused.

Eijirou was currently standing in front of the door of your house. He took a deep breath before he raised a hand to knock, then quickly shoving it back into his pocket, waiting for someone to answer while he hoped it would be you.

"Eijirou!" You greeted happily as you opened the door, looking at your boyfriend with that sweet, reassuring smile he so loved. He was sure that smile would make him do everything, even if honestly, he would yell to the world how much he loved you with no shame.

"Hey, sweetheart" He simply answered, offering his usual wide smile, then walking in as you told him to. You explained your father would be there any minute and sat down on the couch, patting the empty place next to yourself for him to sit down. He obediently sat down, silently. How could he be nervous? Him? The Eijirou Kirishima? The manliest man ever?

Maybe he had a feeling.

The door opened, showing his professor. Classic messy, long, black hair covering his face partially, tired eyes hardening as they fell on his student.

"Mister Aizawa?" The red haired boy let out, widening his eyes. And for a moment, he thought about standing up and simply walk out of the door where he just saw the man coming from, unfortunately too familiar.

"Kirishima?" He answered, his brows furrowing in confusion as he scanned the spiky red haired boy sitting next to his precious girl, his daughter. "What are you doing in my house?"

You were confusingly moving your gaze in between the two men, wondering how they would know each other. But hey, better, it would be less awkward, right? For you, it was completely positive! Wrong. Eijirou was more than ready to throw himself out of the window without your father doing so.

This would end bad, very. Eijirou was sure. But still, for his girlfriend, he thought, letting out a sigh. And for his mother, too, he guessed. Better stay put and try to be nice. Not like he had a bad reputation at school, but having his teacher there felt like having to pass an exam at the end of the year to become an actual hero.
