"One body, two sides. Which is the real face?"
Teenager Park Ji-hoon wakes up one day to a startling discovery: his body has undergone a radical transformation. The once overweight and unattractive boy has become a tall, muscular, and handsome man, looking just like an idol. But how could this have happened?
Ji-hoon wonders if his new body is the key to turning his bleak life around—a life plagued by bullying because of his old appearance. But instead of finding answers about the mystery of his body, he's pulled into something far more dangerous. He finds himself entangled with a mafia overlord, the head of five criminal organizations that run illicit businesses.
As a result of their dirty work, the city of Seoul and its surroundings will suffer. High school students, especially Ji-hoon's friends, will become their victims.
Can Ji-hoon uncover the secret of his body and stop the criminal organizations led by the Overlord?
