(You're Mirio's sibling and its the weekend)

You two got along really well and are close friends, youre even a part of the big three (Four now).

You wanted to ask your brother (Same age, he's a month or so older) about something (If you could borrow his phone charger) so you walked into his dorm, not expecting what you were about to see... Its was a shirtless Tamaki on top of your (Also shirtless) brother Mirio. The were doing some questionable things but you just decided to leave. Its was too late, Mirio saw you and his eyes widened as Tamaki rolled down beside him and looked at you. Tamaki was shocked and embaressed, he hid under Mirio's covers while Mirio got up and stuffed a shirt on.

Mirio: Slightly pissed off "Knock next time dumbass!"

You stood in front of the doorway in shock and surprise, you'd never seen him so angry at you.
