You were a transfer student, you went inside your classroom looking for a seat, then you found those class clowns, you asked.

"Can I sit here?"

You were behind Gojo so he didn't see you, he grins and said.

"Sorry, this seat is the school's property."

Gojo joked and everyone laughed, he finally turned around and saw you, he looked at you up and down.

"Yeah.. you can sit here.."
