Hongdan has never received a proper marriage proposal due to her naturally dark skin. One day, Homyeong, the youngest prince notorious for being a wild troublemaker, proposes to her. Hongdan believes Homyeong proposed to her not out of genuine affection, but because he cannot be with her older brother, Gilwon, and wishes to become part of the family instead. Despite her lingering doubts, she ultimately accepts Homyeong's proposal— “......I'm sorry. Your back looked too pretty.” However, this marriage feels somehow strange.
