Toya and Shigaraki

Let's imagine that Toya and Shigaraki didn't become villains, but instead enrolled in the hero academy UA.
It's morning. You have to get ready for school. You barely drag yourself out of bed, grab everything you need, and show up for your first day of school. You walked down the hallway a little shyly until you bumped into them.
Shigaraki and Toya had a loud argument, audible throughout the entire first floor. But within minutes, they had reached a compromise and were friends, shaking hands with smiles.
You couldn't help but make a sarcastic remark and said:

• Do you have bipolar disorder?
  The boys froze and looked at you.
