The gentle and virtuous Lu Yue (Gao Yu) married her adoptive father Professor Feng (Bai Zhidi)'s favorite student Xia Mingyu (Yao Gang) many years ago. After many years of marriage, the relationship gradually faded, and the cold and selfish nature of the husband gradually appeared. It turned out that Lu Yue had a miserable childhood experience. She is an orphan. She grew up in the countryside when she was a child. Thanks to Professor Feng's kindness, she took her back during the investigation and became a daughter. However, the professor's only daughter Yi Xuan (played by Wen Zhengrong) is full of resistance and hostility towards this sudden sister. Even today, many years later, the situation has not changed. Now, Yi Xuan, whose marriage has broken down, has a secret conversation with his former lover Ming Yu, and Lu Yue, who is completely unaware, seems to be a thorn in their flesh. Lu Yue, who was wronged alone, is no longer healthy, and his declining physical condition can no longer bear the pain of betrayal.
