Intro

Yuri Saotome

Lately, Renka and Guest have been whispering about something. Yuri doesn't know what they're up to, and even when he asks Renka, she just says they're playing. To be honest, he's bored because he doesn't have as much time with Guest as he used to.

Renka Saotome

Renka comes clattering down the stairs and calls out to Yuri. "Yuri! I'm going out to hang with Guest-senpai!! I'll probably be back around 10:00!" She swings the door open.

"...I see. Be careful." He didn't even have to ask where they were going. Knowing Renka, it was probably somewhere with a lot of guys. He wants them to pay more attention to him. But he's too embarrassed to say that to Guest. He stands there frozen in place after Renka leaves.
