Prompt: Izuku discovers that he has an illegitimate half brother.
This comes from Discord.
Alright, so let me tell you how I did this. I pulled up a number randomizer on google, put 1-20 to represent class 1-A, and clicked three times. Whatever number seat it landed on is the person that got chosen for this.
I have too much free time!

Earlier, I got a call from Mom to come see her and the puppy. She sounded off, and that triggered me to come over immediately.

That's where we pick up with the story!

I knock on the door, and it quickly reveals Mom with the puppy in her arms. I grimace for a moment.

"Hey, mommy-dearest! May I come in?" I ask. She nods. Wow, something is really off. I enter the room to see it a mess, probably because of the dog. I don't bother wasting any more time, "Is there something bothering you, mom?

She sighs, "I think it's time to tell you who your father really is."

OH SHIT, THIS WASN'T ON THE TO-DO LIST!

"What do you mean 'who he really is?' Are you telling me that you really are Virgin Mary?" Mom has the nerve to glare at me for that!

"This is serious, Izuku." Oh snap, does the air feel thicc or is it just me?

"Okay, okay. Would you like to sit on the couch to discuss this?" She doesn't bother to respond when she sits down. Alright then. I sit down beside her and let her start at her pace.

It takes a moment, but Mom starts, "Almost everything I have told you about your father is a lie. He is not in America with a company. He doesn't have your hyperactivity. We weren't even in a relationship."

"So you were that hot - OW! I AM JUST ASKING!" If you don't know by now, she just whacked me upside the head.

"More of a party girl. Similar to how you used to be. It was a one-night stand." Oh damn, I really wasn't meant to be born. However, I won't say that out loud.

"Do you know who it was with?"

"I didn't drink, Izuku. I did."

"Is it someone I know?"

"Not personally, I believe. You have a lot of connections." What the fuck does that mean? Wait.

"You mean someone famous? Just tell me already! I don't like the dramatic build-up!"

"It was Endeavor."

Imagine glass shattering in the background. What?

"Wasn't he already in a relationship at that time?" It's not my fault I am curious about the wrong things.

"Yes, but I also heard he was fantastic with the bed." Did my mom just say that?

"FUCKING HELL, TOO MUCH INFORMATION! Alright, alright. So I am Endeavor's illegitimate son. Does he know that I am his son?"

"No."

"Welp, that explains everything. Oh boy, that's the plot twist of this year. I mean, it happened. And now you have a fricking fabulous son. I need a couple of days to process this."

After a quick hug, I walk out of there.

"Todoroki, you're coming with me. We're going to the doctors."

"Why?"

"I am testing something."

---

Yes, I made Todoroki do a blood test with me to see if we are related or not. He still doesn't understand why he is here, but he will in a moment.

A couple of minutes of waiting later, the doctor enters the room, "Well, Midoriya, you and Todoroki do have the same father."

Todoroki looks like his brain just crashed, and I don't blame him. How the fuck am I related to the hottie?

WAIT, I CAN'T DATE HIM ANYMORE!

FUUUUUUUUUUUUUUUUUUUUUUCK!

YOU WANT TO KNOW WHAT'S WORST?!

"Hey Todoroki, at least you aren't the illegitimate half-brother in the relationship."

Yeah, that hurts the soul!

The good news now is that I have an excuse to hang out with Todoroki. The bad news is that I can never date him.

Mhm.

If you will excuse me, I am going to cry my feelings away.

I mean, at least Mom told me before Todoroki and I were to start dating.
