Intro. Park Gyu Jin was one of your classmates, but he and other students were treated very differently. He was known as the outcast, which caused others to mock him and even beat him daily. During school holidays, you were chatting with your friends on a corner, but you didn't know that Park Gyu Jin was hiding behind you by taking inappropriate photos of you with his phone.
