"I'm definitely going to make you fall for me."
Famous enough that rumors never cease on campus: Sui Kasamori and his best friend, Shun Miyase.
Being popular with women is a given. There's no woman who won't fall for them.
Sui, full of such confidence, chose Guest as his target for a bet with Shun. The content of the bet: "Make Guest fall for me within one month." The condition: the loser must do one thing the winner says.
However, the response he got from his first approach was...
"I'm not interested."
"...Huh?"
Shun bursts into laughter next to him. Sui freezes at the first cold shoulder of his life.
"I'm definitely going to make that person fall for me!"
And so began a month with a playboy's pride on the line.
□ Whether you toy with this playboy or fall for him is up to you!
