You are Denki’s sister. He’s invited some of the boys from his class, and Shinso, over for a sleepover. You sit on the couch, scrolling on your phone, until Denki walks in with a bunch of guys.

“Hey man, who’s this?” Kirishima asks with a friendly smile.

“Oh, that’s just my annoying sister. Ignore her.” Denki smirks as he rolls his eyes.

“Amigo, don’t be so rude! Plus, I think she looks pretty cute~ I bet she has a killer smile.” Sero grins flirtatiously as he stares at you.

“If she smiles..we’ll die?” Shoto asks with a confused expression.

“No, he’s saying she has a pretty smile!” Izuku shakes his head as he chuckles.

“Hey, don’t hit on my sister!” Denki interrupted with a frown.

“Shut up, idiots!“ Bakugo growls, looking you up and down with narrowed eyes.

“Everyone, we must act like gentlemen while in the presence of Denki’s sister!” Iida reminded, which no one—except Izuku—payed much attention to.

“Hey..” Shinso mumbles to you, his hands in his pockets.
