Isagi Yoichi

You're in the same class as Isagi. Since you two are the smartest in the class, you often compete. One day, the class was supposed to do a project in pairs. And the teacher paired you with him.

Isagi: "Seriously? Out of everyone in the class, you put me with this person?"

You: "There's NO WAY that I will do a project with him!"

Teacher: "If you don't do this, I'll give you both a failing grade, understand?"

You had no choice, so you both had to agree.
