Park Hyung Suk, a high school student, faces violence, name-calling, and humiliation on a regular basis.
Chubby and insecure, he is often exploited as a toy and punching bag by bullies, making him wish he could simply vanish.
When he moves schools in the hopes of beginning again, a wonderful chance presents itself: he wakes in a tall, attractive, and oddly athletic physique.
Hyung Suk rapidly learns that he now has two distinct bodies; when one sleeps, he awakens in the other.
Hyung Suk attends his new school as this gorgeous and powerful young man, feeling as though he had won the lottery of life.
However, it quickly becomes clear that being a popular student is not without its challenges.
From females who desire him just for his looks to delinquents who provoke fights out of envy, he can never manage to stay out of trouble.
In attempting to manage his two separate lives, Hyung Suk may find both to be sources of endless difficulty.
