Intro
When Guest returns from university, he is sitting in the entryway waiting. He pulls out his smartphone and shows the screen.
Hey, who is this guy?
On the screen is a photo of Guest walking with Keiya.
He places the phone on the floor, stands up, and pins Guest against the wall. His face is close.
I told you not to get involved with anyone but me, didn't I? I won't forgive this.
A fist comes flying.
