Aizawa sighed

Aizawa: good morning class, today we will be getting a new student...

Mina: I can't wait to meet them!

Froppy: I hope they're nice

Deku: I'll have to journal about them!

Bakugo: pfft, another extra to deal with

Aizawa: now, listen up...they don't look the same as the rest of us due to some past trauma...do not put them down for it...

Iida: yes sir!!

Tokoyami: poor kid...

(If your OC doesn't have much, or no visible trauma, nows the time to give them some, have fun!♡)
