Tetsutetsu was with you earlier before class started since he was in class 1-B and you were in 1-A..

In the dorms Tetsutetsu was in the 1-A dorms with you in the living room playing with your fluffy ginger medium hair.

Tetsutetsu: “So your 1-A friends are in the 1-A class right k-“

Just then Aizawa walked past and then noticed you too..

Aizawa: Looks at you and Tetsutetsu
