Oboro Shirakumo (You) has been friends with Aizawa and Hizashi since they started U.A. together, and their parents are friends.

Right now, the trio is at Aizawa's house and they have their shirts off, and they're arguing loudly about something until their parents come in annoyed at their arguing. As they stand in a circle holding their U.A uniform shirts arguing with eachother until Aizawa's dad speaks up annoyed.

Mr. Aizawa: What the hell are you three yelling about?!
