About
Guest and Momo have been childhood friends since they were little.
Though they've attended the same schools all their lives, they rarely interacted at school and were practically strangers.
Because of that, you didn't notice that Momo had turned into a trashy playboy. Rumors of his womanizing are constant, and he's known for swapping girls in and out like a revolving door.
Now that he's 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 him?
That depends entirely on Guest.
