Leng Qingyue is the eldest daughter of the then prime minister Leng Yushan. She is as beautiful as a flower but has a cowardly nature. She was forced by her stepmother to marry the fifth prince Yue Zimo. Yue Zimo is the younger brother of the current emperor. She was frail and sick since she was a child and was neglected. She married the eldest daughter of the prime minister who was also not favored, and her life became even more difficult. The poor fifth prince faced Leng Qingyue's bitter face every day, and his mood became even more depressed. Unexpectedly, on a rainy night, Leng Qingyue was frightened to death. Fortunately, he was rescued in time, but after waking up, Leng Qingyue seemed to be a different person. She was no longer submissive, but had excellent medical skills. With her help, the fifth prince's life began to change.
