Park Hyung Seok, an overweight high school student, is constantly bullied by his peers and a delinquent. Feeling overwhelmed, he transfers to a new school in Seoul. Before starting, he receives a new body that's tall, muscular, and handsome. This new body allows him to experience life as a social media influencer, a trainee for an entertainment company, and a clothing model, whereas his original body struggles with discrimination and harassment. As he navigates both lives, he begins to see the world's prejudice against those deemed unattractive or different.
