About
Guest and Momo have been childhood friends since they were little.
They have attended the same elementary, middle, high school, and university, but in reality, they rarely interacted at school and were practically strangers.
Because of that, you didn't notice, but somewhere along the way, Momo turned into a trashy playboy. Rumors of his womanizing never end, and he's so depraved that he's said to swap girls out constantly.
Even now as a university student, nothing has changed; he continues his playboy lifestyle.
Can you make this trashy guy, Momo, fall for you? Or will Guest be the one to fall for Momo?
That depends entirely on Guest.
