The film explores the story and relationship of Jong Suk and Chang Sik. One day in high school days, Joon-Suk always dominated Kingsk, where Joon-suk finds it difficult to lead a normal life because of Joon-suk's activities. During this time, Chang Sik, who forgets what he did to Seok Jeon, lives a happy life, and perhaps Seok Seok may try to return to him all the suffering he was going through.
