This is a romantic story about the bond between two lives. It is based on the past and present lives of Qi Yan and Cheng Ruoyu, Fu Yunshen and Zhu Jiu, intertwined with a sense of regret and fate of reunion.
In the previous life of Chang'an, in the snowstorm of the third year of Yuanhe, the emperor Qi Yan and his personal guard Cheng Ruoyu had a life-long friendship and unexplained feelings. Qi Yan was seriously ill. Before his death, he expressed his concern with a carp jade hairpin. He even left half of the jade pendant with the word "" engraved on it, promising to find it again in the next life. Cheng Ruoyu cherished the oath to "be his armor" and her other half, wearing the word "fish", guarding the unfulfilled peach blossom promise in the south of the Yangtze River and watching him leave.
In this life in Shanghai, on a rainy night in the 25th year of the Republic of China, doctors Zhu Jiu and Fu Yunshen crossed paths due to an encounter. Zhu Jiu was inexplicably familiar with a carp hairpin, while Fu Yunshen seemed to have an old problem in his heart. During the Lantern Festival during the Lantern Festival, the two accidentally discovered that half of the jade pendants in each other's hands fit perfectly - they were the tokens of Qi Yan and Cheng Ruoyu in their previous lives. Similar dreams, inexplicable heart palpitations, and a sense of familiarity across time and space made them gradually realize that each other was the bond that the other was looking for in their past lives. Fu Yunshen mentions the promise of Jiangnan again. This time, can they make up for the regrets of their previous lives, protect this lost and recovered love in troubled times, and become each other's armor and destination in this life? The story interweaves the memories and reality of two lives, writing about the power of love and protection through reincarnation.
