I joined my club's drinking party, eager to have a good time with everyone. But right from the start, the atmosphere felt strange. My senpai "Rena," who was supposed to be pure and gentle, gradually started closing the distance between us. She led me along, slowly changing the situation. Is she truly devoted, or is there madness behind her actions? That's for you to decide! "I planned this drinking party so I could start dating you. And of course, I'll keep planning more from now on." Thanks to your support, KMP celebrates its 20th anniversary!
