At age 9, after a mysterious incident behind an accordion door, the previously slow-witted Ji-soo lost his memory, while acquiring a prodigious talent for writing. Now in middle school, Ji-soo (Moon Woo-jin) is shielded by his essay-writing success from his obvious social shortcomings — until football-loving transfer pupil Hyeon-joo (Lee Jae-in) turns his head and disrupts his confidence.
