Taepung Gang is a transfer student with a dream. He's going to become the number one fighter at his new all-boys school, and he's got the skills, muscle, and notoriety to make it happen. He definitely wasn't supposed to swap places with Princess Lily, a peace-loving royal from a fairytale land—without either of their memories! Will Lily fulfill Taepung's dream of becoming the school's best fighter? Will Taepung survive his new life as the cursed princess? How does a delinquent become a princess anyway, or a princess become a delinquent for that matter?
