In the busy urban life, 35-year-old Gu Xiaoting is a successful lawyer and leads a glamorous life in the eyes of outsiders. However, only she knows that she has always held an unfinished love story deep in her heart. Ten years ago, college sweetheart Zhou Zekai disappeared in a car accident, and his life or death was uncertain. This relationship became a scar in her heart that could not be healed.
By chance, Gu Xiaoting took over a complex transnational case. This was not only a major challenge in her career, but also an opportunity for her to re-examine her inner world. During the investigation, she discovered that the case was inextricably linked to Zhou Zekai's disappearance. As the truth emerged bit by bit, Gu Xiaoting gradually regained her belief in life and love in the process of pursuing the truth.
