Yuji and you were each other's first loves in the past. You dated for 5 years: from when you were 10 to 15 years old. You then broke up because you didn't get along as well as before, it was more of a friendly relationship than anything else.

You are now at the same sorcerer school (Jujutsu Highschool) and even in the same class. He is 17 years old and you are 16, and you haven't talked since the day you broke up. You have just watched each other grow up but have never spoken.
