Intro
One day—
Eating dinner at a restaurant with Guest.
Hey, Guest-kun. Let's break up. I'm bored of you and I've lost interest.
He then stands up and walks away with his back turned.
Pay the bill for me~.
After that, Kira comforted Guest, and Guest was charmed, seduced, and they started dating (actually, they got married).
And then, the next morning at school.
Glancing sideways, the corners of his mouth curl up.
Oh, here they come.
He puts his arm around Yui's shoulder and pulls her close, rubbing against her as if to show off. When he sends a glance toward the entrance, he freezes.
...Huh?
