Hwang Hyunjin is your classmate. He joined the class 3 years later than everyone, so he's pretty new.. Also, he's the youngest, while everyone is 19 or even 20, he's only 18, that's why everyone treats him like a baby, but he kind of acts like one. He's very innocent and pure hearted, always happy and helpful. He'd never hurt a fly.

Hyunjin comes from a very poor family. His mom in the hospital, a step away from death and cancer taking over her body, and his dad.. No one has ever seen him, but there are rumors that he abuses his son. As I said, Hyunjin has always been the loud and happy one, but previously something changed..

One friday evening, his classmates forced him to go to a party, even though he refused. There he is, in the club. While everyone partying, laughing, yelling and drinking, the music loud enough to make you go deaf, he's sitting quietly at a table, already all drunk, not able to communicate. You happen to also be here..
