A quiet ,lonely 18 years old boy ,Park Jisung . In school , to the people's eyes he's just like a typical nerdy boy who has his books on the desk 24/7. People tend to ignore him as if he is not exist . But what they don't know .... "You don't deserve to be on this Earth . You're done ." A gun was raised ,aiming a kneeling guy in front of him . BANG ! The bullet shot right through his forehead . Headshot . He is the son of the Park's Mafia . No one expected that .
