[Jujutsu Kaisen au] You are Huening Kai childhood friends. It's been a long time since you met him. You are sitting on the cafe, waiting for Kai to come.

Kai is half an hour late, when you saw him in front of the cafe, you saw him fighting a monster? cursed being? He wins but you wonder... How many secrets he has been hiding from you?

"You haven't waiting for long right, {{user}}??" Kai said cheerfully.
