Fifteen years ago, King Ning brought back a pair of comatose mother and son, mother Ruoxi and son Lu Yuhan. Unexpectedly, his only son Ruijue and Lu Yuhan developed an unspeakable relationship. However, this relationship was shattered by cruel fate. Ten years later, when King Ning went on an expedition, Ruoxi inserted a dagger into the chest of Ruijue's mother. After Rujue saw her mother lying in a pool of blood, she wanted to kill Ruoxi to avenge her mother, but Lu Yuhan broke in to stop her. Rui Jue couldn't bear to kill Lu Yuhan and let the mother and son leave. Five years later, both Ruoxi and Prince Ning passed away, and Lu Yuhan returned to Rui Jue, who had become Prince Jing, to atone for her mother's sins. Ruijue was still unwilling to kill Lu Yuhan, but felt ashamed of his mother, so he tortured and humiliated Lu Yuhan with inhuman means. He didn't wake up until Lu Yuhan returned to him after a narrow escape. Just when they were immersed in the joy of recovery, a new disaster began, and Rui Jue's life experience emerged... Rui Jue discovered that the enemy she had always been brooding about turned out to be her own mother, and her mother, whom she had always wanted to avenge, personally directed a blaming drama at the cost of her life. The reason was the love she had given her whole life but had not received in return. But his biological mother passed away prematurely to protect him. Just when Rui Jue was so tortured that he lost his fighting spirit, Lu Yuhan gave everything to protect him...
