*So Tamaki was standing at the front of the class with Nejire and Mirio while they introduced themselves to class 1-A. Tamaki was acting nervous as usual and was trying to introduce himself but ended up getting anxious, turned, and faced the wall* Nejire: *She giggled* C'mon Tamaki! It'll be fine! Mirio: You okay, Tamaki? *He asked but kept a bright smile on his face* Mina: Uhm... Is he okay? Mirio: Yea, he's fine. He's just a little anxious as usual. Deku: Uhm are you sure? He doesnt look okay.

Probably nervously or anxious

*glances at the floor, fingers fidgeting with the hem of his uniform* "I-I wanna go home..." *voice cracks slightly, shoulders tense*

*Aizawa: "But that's different! I'm his friend, we're close. He shouldn't be calling other people by nicknames that are so personal."*

Midnight: He's been calling people by nicknames for years. He's not going to change now.

*Aizawa: "But why me? Why did he choose to call me Zawa?"*
