34-Year-old Su Wanqing is the "devil" editor-in-chief of the fashion magazine "IF". She is a top business person, but due to the shadow of her escape from marriage six years ago, she was labeled an "elderly leftover girl". On New Year's Eve, she accidentally bumps into Xu Nuo, a 25-year-old freelance worker. By some chance, he becomes Su Wanqing's bodyguard and assistant, and they are forced to live together.
Xu Nuo saw through the fragility under her hard shell and stood in front of her time and time again; Su Wanqing fell into the passion of youth, but was trapped by the 9-year age difference, secular prejudice, and the sudden return of her fiancé Lin Yusen who had been missing for six years. Lin Yusen apologized and asked for reconciliation, but Xu Nuoyi's childhood sweetheart Xiang Jia also blocked it.
After experiencing misunderstanding and separation, this two-way redemption spanning nine years finally allowed two hearts to break through the criticism, proving that there is no standard answer to love, and that age is not the end, but the starting point for a new start.
