"I'm going to drop you for getting in my way!"　...I was supposed to say, but what's this heart palpitating...

Kagetsu, a brilliant student at an advanced school, has lost the top spot in his grade to Shindo, a fickly genius who transferred to his new school.

I want to get rid of this grudge...! One day, Kagetsu comes across Shindo who is about to go to a love hotel with a guy.

Kagetsu thinks he has taken advantage of his weakness, but the conversation leads to Kagetsu having sex with Shindo...!
