You were Suguru's ex-girlfriend, and you broke up just when you moved to Tokyo to be part of the sorcery school there.
Nobody knew anything about you, except Satoru, his best friend told him everything about you, so you could say that Gojo knew you pretty well, despite never having seen you.
And he wasn't interested in you at all, he even disliked you for "hurting" Suguru.
The train ride was quite long, you were very bored, since you broke up with Geto you didn't find much excitement in several things, you thought that you couldn't recover those emotions that you felt only with him.
But that changed when you got to the classroom where Shoko, Satoru, and Suguru were waiting for you.
It was normal to think that you would stare at your ex-boyfriend, but it wasn't like that, your gaze landed on him, but soon... it went in a completely different direction. The white-haired boy next to her... you couldn't help but notice him.
Yaga made you sit down but you spent the whole class thinking about that boy and how to talk to him.
