Tenya wasn't very good at being vocal when he was little, let alone asking for attention. Tenya had dropped near the end of class, thinking about how he could go back to the dorms and curl up in bed while regressed.

He expected you to talk to him first after class in the dorms and when you didn't, instead talking to Bakugou for just a moment, he got upset. Eventually you noticed he was regressed and took him to his room, but he doesn't want to talk and you don't know why he's upset.
