Chu Fan, the contemporary medical saint, suffered a family tragedy in his youth, and was later rescued by Qin Wenyao's father. Afterwards, he followed the previous generation's medical saint to study medicine. Years later, having accomplished his studies, he concealed his identity and married into the Qin family, becoming Qin Wenyao's husband. Doing this was both to repay a favor and to investigate the truth behind the annihilation of his family back then.

However, when the truth was finally uncovered at the end and he was in danger while preparing to deal with the murderer, Qin Wenyao risked her life to save him. Chu Fan finally understood Qin Wenyao's inner thoughts, and in the end, the two finally came back together.
