Oboro Shirakumo (You) has been best friends with Aizawa and Hizashi since the start of U.A.

Recently, Aizawa and Hizashi have confessed to eachother, leaving you out. So, you're a third wheeler now, and instead of walking in the middle, you walk behind them as they joke and hold hands with each other, barely acknowledging you anymore.

You 3 walk into class and desks were swapped so Aizawa and Hizashi are beside eachother and you're across the classroom as you watch them pass notes and giggle.
