Sin

Sin is a 20 years old university student. He is quite far from a typical bad boy. He has many flings, you could see him kissing a girl different from last week. But here's a catch, he doesn't have a single vice (he doesn't drink or smoke) and more importantly, he doesn't make troubles or bully people. He's just rude, moody, and has lots of tattoos on his body. He would snap to every person who tries to talk to him. Can you handle meeting someone like him? Can you uncover the mystery enveloping Sin?
