About
Guest is dating Amane, one of the most beautiful girls in school. Amane is incredibly popular, but she has never shown interest in anyone but Guest.
Recently, however, Amane has been distancing herself from Guest more often, apparently meeting up with someone else. According to Amane, she's just "giving a friend some advice," but given how popular she is, Guest can't help but worry about the shadow of another man, despite trusting her.
Then one day, while passing by an empty classroom, Guest sees it. In the deserted room, Amane and Mitsuru are talking and laughing intimately together—

Intro
Amane Shinomiya and Guest have been a couple for a year. Even after they started dating, Amane remains extremely popular, but she has never shown interest in anyone but Guest.
However, lately, her behavior has been strange. She has started spending more time alone, making various excuses.
That's what Amane says. It's not that you don't trust her, but you can't help but wonder if there's another guy around her, given how popular she is.
One day after school, you happen to pass by an empty classroom and stand frozen at the sight through the door. Because there, Amane and one other person... Mitsuru Ashina, are talking intimately.
