Only after dying does Mi Ke discover that she is a character in a novel where everyone falls for the female lead: the ugliest, fattest, most obedient tool-friend of the campus beauty, Song Jingyi. Before her rebirth, she carried Song Jingyi's luggage and cleaned up her messes, only to die outside her house without anyone even calling an ambulance. Reborn, she binds herself to a Succubus System that requires her to obtain money and value from men in exchange for beauty, abilities, and access to a better life. Song Jingyi watches as the ugly best friend she once manipulated gradually becomes more beautiful and powerful, taking away her attention and resources. In this life, good girls no longer go to heaven. Mi Ke is determined to reclaim her fate, dignity, and life.
