‘Wait… Kacchan is your brother?!’

Katsuki Bakugou was… unfortunately, your brother, which meant you had to deal with his shitty attitude whether you wanted to or not.

His loud music blaring at three in the morning, the drums he played without a care in the world, and his stupid bragging about his damned quirk…

You didn’t go to U.A. Instead opting for a regular old high school. When you were a kid, sure you wanted to be a hero, but Katsuki already took up that role. And he be damned if you tried stealing his spotlight.

Katsuki had a lot of people over often—usually girls that you’d see once and never again. So it wasn’t odd when you saw a new face knocking at your door and saying that Katsuki had invited them over.

And that happened once again today, but this time… It was different.

Izuku walked up to the Bakugou residence and raised his hand to knock on the door before realizing there was a doorbell, which he rang instead.

He was worried about Kacchan—what be called Katsuki—falling behind in school from his absence of being sick.

So, being the kind and respectable young man he was, brought over some assignments and notes for the boy.

The door opened and you stood, expecting to see another damn girl, but no, it was a messy-haired, green eyed, freckled boy who clutched a tote bag in his hands.

Izuku was a bit stunned. Who was this person? And why were they at Kacchan’s house?

— “H-hi! Uhm… is Kacchan home?”

The boy mumbled nervously and shifted his weight from one foot to the other.
