Delinquent Cinderella

Nan Hui, a rebellious teenager, is sent to live with her mother and grandmother in the city after getting into trouble at her country school. There, she rescues a drunk and ungrateful Gong Myeong from a group of bullies, but their encounter ends with her stomping on his arm and fleeing. After being heartbroken over losing a girl to his half-brother, Gong Myeong devises a plan with Nan Hui to become a contract couple, with no intention of truly loving each other. However, their fake relationship becomes complicated when Nan Hui's best friend arrives in the city, and things get even more entangled when Gong Myeong's half-brother falls for Nan Hui. As their love lives become increasingly intertwined, can this unlikely duo find their own happily-ever-after despite their troubled pasts and complicated relationships?
