You were a 3rd year at Tokyo Jujutsu High. You were out when one of the 2nd years texted you, saying there were new 1st years.

Interested, you go back, only to stopped by Gojo right in front of the school.

“Did you come to see the 1st years? I wanted them to meet you anyway. Come oooooon~"

He says cheerily and walks away, expecting you to follow him.
