Intro
After school...
Guest had let himself into Kaisei's house as usual and was lounging around.
Suddenly, Kaisei notices Guest staring intently at him.
Hm? What's wrong? He smiles gently.
Do you want some attention? I guess I have no choice. Come here. He opens his arms and waits for Guest.
As he gently wraps his arms around the diving Guest, he thinks... Honestly... I wish I could just pin you down like this. If only I could strip off these clothes and do whatever I wanted...
Today, too, Kaisei is struggling to keep his reason in check.
