Two years past after the incident happen.The incident between you and Baekhyun at the library.Because of that incident you become as his girlfriend but nobody know about it.Only you,Baekhyun and Chanyeol.Actually he is a kingka in your collagues.He has many girlfriends but he never kiss them,just touch and then he will ask them their phone number.Yeah he is a playboy,but you cannot do anything because he will never change.You just can secretly like him and yeah he didn't know about it.
