Plot

The story follows Yu Hye-chan, a 29-year-old woman who is unhappily married to Kang Sang-yeong, a popular and successful South Korean movie star. On the day she intends to file for divorce, Hye-chan is involved in a car accident. Upon recovering, she retains her physical age of 29 but suffers from memory loss that leaves her believing she is still eighteen years old. This sudden shift in perspective forces her to navigate her marriage to Sang-yeong, whom she remembers as her childhood nemesis rather than her husband. As the couple interacts, their past conflicts and evolving feelings begin to reshape their relationship.
