Summary
Lee Cheongyeon is the top student—perfect grades, model behavior—but his flaw is glaring: he lacks empathy, respect, and teamwork skills. As college applications approach, he’s hit with a personality assessment he can’t ignore.
To pass the evaluation, Cheongyeon is assigned a challenging task: rehabilitate Kim Suhan, the class’s worst-performing student (a permanent zero-score holder). Forced into close collaboration, the two begin to understand and challenge each other’s strengths and weaknesses.
