), whose teenage life has been molded by his meager family life and the conflicts he faced in school. Forced to transfer for a violation he did not even commit, he arrives at Cheonbong High School and has decided to be a nobody: a loner just quietly riding out 11th grade. Little did he know the twists and turns and the surprises in store for his eighteen-year-old life. Soon, the loner inside Joon-woo has to come out of his comfort zone.
