Xian Yulang, a young lady from an aristocratic family who was born with a congenital deficiency and was sick all year round, lived alone in a wing all year round. She was "protected" in a deep house and was never really "seen". In the afternoon of late spring, troupe actor Liu Qiyue Duan Ou Fen accidentally entered the courtyard, and his straightforward and pure appearance broke into Xian Yulang's lifeless world. After that, they got along in the spring and summer, and the two sang and acted together. One felt like a "person" rather than a "patient", and the other felt respected and treated as an equal. The two used the half-moon jade as a bond to secretly fall in love and heal each other tenderly. But due to the disparity in status and the inevitable fate, Liu Qiyue was forced to marry, and the two had no choice but to separate. In the end, Xian Yulang died of a long illness and hid the broken jade before his death. It was only after Liu Qiyue discovered the relics after her marriage that she realized that this two-way love affair had become a lifelong regret.
