Mu Wan, the legitimate daughter of the Prince of Zhennan, mistakenly believed in someone else in her previous life. In order to marry the eighth prince, Situ Che, she did not hesitate to force the prince Situ Jue, who was engaged to her, to break off the engagement. In order to fulfill her wish, Situ Jue asked himself to guard the border and did not return for three years. Unexpectedly, Situ Che only wanted the military power of the Mu family, and after he succeeded, he trapped the whole family of Zhennan Palace, and dragged Mu Wan into an ice cellar in the cold winter and tortured him to death.
On her deathbed, Mu Wan realized that Situ Jue was not the cold and ascetic person rumored to be. He had endured it for many years, silently guarding her, and even stayed unmarried for her whole life. After learning of her tragic death, he followed her after killing his enemies.
With endless regret, Mu Wan was reborn and returned to the age of her hair. In this life, she tore apart scumbags and scoundrels, vowing to protect her family and bring back the prince whose heart she had broken. Faced with her sudden advances, Situ Jue was full of doubts, thinking it was her new trick, and kept avoiding him.
From temptation to honesty, from misunderstanding to deep love, the two clearly see each other's feelings in each confrontation. But Situ Che, who suddenly woke up, became hateful because of love, and wanted to harm Situ Jue, but ultimately ended up with an unhappy ending. In this life, Mu Wan and Situ Jue will never miss each other again, holding hands and growing old together, guarding the mountains and rivers together.
