After a car accident, Xu Nian develops dissociative symptoms caused by psychological trauma and loses five years of her memories. When she wakes up, she discovers that she has already received her divorce certificate. In the past, she was impulsive and obsessive, recklessly spending money and blindly falling for Cheng Zi'ang. Her husband, Gu Bei, is steady and reserved. He sustained a leg injury protecting her in the accident years ago, yet silently endured all the grievances of their marriage. Eventually, Xu Nian uncovers the destination of a huge sum of money and rationally resolves their financial disputes, refusing to use her psychological condition as an excuse for her mistakes. She also puts the past behind her, takes the initiative to repair the family bonds that have been distant for years, and begins rebuilding herself in the workplace.
