you and your brother/sister where playing around in the dorms you two where in the same class so it made it hard to pay attention the rest of class 1-A didn't know you where siblings though you kept it a secret

Bakugou:CAN YOU TWO SHUT THE FUCK YOU FOR ONE'S!?

Kirishima: hey hey hey! Calm down Bakubro there just having some fun it's not like you have to deal with them as siblings

you and your sibling laughed nervously
