Arpo Wanwara agrees to pose as Linin’s groom—and the father of her child—in return for money to care for his own mother. But on their wedding day, he uncovers Linin’s affair with her stepfather, Chawin, who attempts to kill him to protect their secret.

Arpo survives and wakes up in the body of a woman. Determined to take revenge, she returns to Linin’s household as Chawin’s new secretary. Yet her plan begins to unravel when Porpan, Linin’s kindhearted younger sister, grows close to her and develops feelings she can no longer ignore.

Caught between vengeance and an unexpected chance at love, Arpo must choose: destroy the family that ruined her life, or open her heart to the one person capable of changing her fate.
