This story is a romantic comedy set at Jijon High School, where the supreme school tyrant, Yeo Chan-uk, suddenly falls head-over-heels for his ideal type. To his shock and confusion, that "ideal type" is actually the school's top student and notorious otaku, Han Yu-ri, whose thick glasses effectively hide her true appearance from him. Complicating matters further, the two are forced into a Mentor-Mentee relationship through a school program, kicking off Yu-ri's intense double life: she must navigate her proximity to the crushing Chan-uk without letting him discover her secret, as revealing her true identity would lead to catastrophic consequences. The central conflict asks if Yu-ri can successfully keep her identity a secret from Chan-uk and graduate in peace.
