Synopsis
In 2023, Han Yi-joo (Jung Yoo-min) is the naive adopted eldest daughter of a rich family. Despite their cold and uncaring behavior towards her, she works hard for her family's love and approval, especially her mother's (Lee Jung-hye), for whom she makes imitations of famous paintings as a hobby. One day, Yi-joo discovers that Lee Jung-hye has not only been defrauding clients by selling them the imitations but has also framed her for the crime; later the same day, she finds out that her husband, Yoo Se-hyuk (Oh Seung-yoon), has feelings for her younger sister and has filed for divorce.

Feeling overwhelmed, Yi-joo runs away and gets into a serious car accident. Although she survives, she is subsequently murdered by Jung-hye's assistant in her hospital bed. She then wakes up in 2022, exactly one year before the accident, when she's still engaged. Deciding to take revenge on both her family and fiancé, she seeks out Seo Do-guk (Sung Hoon), the man her younger sister has a crush on and proposes to him. He agrees to the marriage but with a condition: to win the trust of his grandmother.
