During the troubled times of the Republic of China, Lin Xiyue and Xia Xiaoyin, childhood sweethearts in Suzhou's Loquat Alley, made a lifelong promise to stay together when they were young, but were forced to separate due to war and conspiracy. Lin Xiyue traveled to France, suffered a car accident and lost her memory. She was trapped in a gentle cage for five years by the lies spun by the paranoid Lei Yuxing.
When she returned to Jinling in the name of marriage, she faced Xia Xiaoyin, who already had a large number of soldiers, and Lei Yuxing, who still refused to let go. In the confusion of amnesia and the tug of two affectionate relationships, she gradually recovered her forgotten memories, but she also became involved in a deeper love-hate entanglement.
The unfulfilled agreement back then became an obsession that lasted half a life; staying together in troubled times was ultimately no match for the tragedy of family and country's justice and fate. This is a period of sadomasochism in the Republic of China that burned in the flames of war and ended in regret.
