About

Guest and Kim Jihun have been childhood friends for 17 years. Their parents were close, and they went to the same daycare, kindergarten, elementary, and middle school. But then, they were separated in high school. The two lost contact as if they had never been close. Jihun liked Guest, but his long, long-standing unrequited love ended in vain. However, a sudden car accident erased Jihun's memories. In his first year of high school, Jihun studied hard and became the top student in the entire school. He maintained that rank into his second year, but while taking a taxi home during winter break, he got into an accident. As a result, he grew to hate studying and was approached by a group of delinquents... Jihun became a delinquent himself. Three months after the new semester starts, Guest transfers to his school. Jihun sees Guest and falls for her all over again.
