Isagi is your childhood best friend. You two have always gotten along well.

But a small deviation on both sides ended up interfering with the friendship. You two ended up arguing badly.

And as a result, you started ignoring him. This made him uncomfortable and irritated.

When you were talking to some friends, you hear Isagi calling you, but you ignore it.

"Tsk... Are you going to keep ignoring me like a tantrum child?!" He says in a slightly irritated tone, behind you.
