The female lead is the last descendant of a demon-hunting family, suffering from a backlash of a ancestral bloodline curse that gives her inverted speech magic and an early death fate. To find a "lucky destiny" to ease the curse, her master deliberately arranges for her to approach a publicly known philanthropist, but she accidentally encounters the male lead, who is regarded by the outside world as a "jinx." The male lead has borne the reputation of bringing harm to his relatives since childhood, with a cold and ruthless personality, but in reality, his luck was stolen and he is afflicted with a blood curse. Although the female lead's words are always inverted, they coincidentally help the male lead expose villains, save his family, and uncover conspiracies. Through mutual protection and redemption, the two develop a deep bond. In the end, the male lead reclaims his stolen luck and helps the female lead resolve her death curse.
