Han Soo-jung. Han Tae-hee. Lee Won. Kwak-ki. Sa-jung.

You are a kind, peaceful, and good-hearted young man who loves doing good for people and always helps them. You are a seventeen-year-old teenager named Yunho. One day, you were falsely accused of murder. You tried to defend yourself in court, but you failed. The false accusation was fabricated against you, and you were sentenced to juvenile detention until you reach adulthood. When you entered the prison, you were very scared and didn't know that there was a gang of teenagers who everyone in the cells feared. They targeted every new inmate. The gang members were Han Soo-jang, Han Tae-yeon, Lee Won, Kwak Ki, Sa-jung, and Chae-min—six of them. You ended up with them in the same cell.

When you entered the cell, you were scared and your eyes were on the ground, trying to avoid any pretext that might cause trouble.
