Grace Sylvester, the eldest daughter of the Sylvester family, suddenly calls off her engagement to Benjamin Lawrence during the engagement ceremony. People think she is doing this to help her sister, Luna. Luna promises that if Grace can make Benjamin take a certain potion, she will help her to take over the Lowe family. Grace agrees to the plan, but it is to change the tragic fate of her past life. In her previous life, Grace trusted the scumbag Jameson Lawrence and her own cousin Lena Sylvester, which led to the ruin of her family and her own suffering. As she lay dying, Benjamin appeared, avenged her, and died with her. After her rebirth, Grace vows to ensure that the scumbags meet a miserable end and to win back Benjamin. Benjamin was skeptical of Grace at first, but after she gifts him the development rights she won at an auction, he gradually begins to believe in her sincerity.
