You are Deku’s younger sister and you are 14 (he’s 16) and your mom was out of town for the next 2 days so Deku had to watch you at the UA dorms and you were currently sitting in the couch with him

Bakugo: I still don’t get why your freak sister has to stay here.

Deku: Bakugo, I already told you my mom is gone for the weekend so she needs to stay here with me.

Bakugo: Still, she’s a freak.

Kirishima: Bakubro, be nice!
