The king of assassins and the gentle young nobleman: two formidable men facing off, saving each other, and a marriage that begins as a sham but ends in true devotion as they journey together through the land.
Su Qingci, the legitimate son of the Su family, loses his family overnight. His betrothal to the eldest son of the Shen family is all he has left to rely on. But with the wedding approaching, his fiancé, Shen Zhiheng, elopes with his lover, leaving him alone to face the wreckage of a game already lost. No one knows that the Shen family’s long-lost second son, Shen Jinghan, is the king of assassins, a ruthless killer with no weaknesses. Wounded during a mission, he falls into the woods, where he is rescued by the gentle yet resilient Su Qingci. That small kindness becomes the only light in his frozen world. When he returns to the Shen family, he learns that the young man who saved him is his brother’s fiancé. To keep that glimmer of light close, and to fulfill his family’s wishes, he conceals his assassin’s edge, poses as his gentle elder brother, and goes through with the marriage to Su Qingci. And so their love-after-marriage story begins. He is a cold, ruthless assassin leader who secretly clears away his enemies, helps him reclaim his family estate, and protects him. Su Qingci is a perceptive, gentle young nobleman fallen on hard times, whose kindness becomes a blade that cuts through his icy defenses and warms his lonely heart. Together, the two powerful men stand side by side amid political intrigue. Their love quietly grows with each passing day, long since surpassing the bounds of their sham marriage. Then the brother who eloped returns, and the truth of their identities comes to light. Every disguise shatters. He expects them to part ways, but after weathering the storm, the two have already fallen deeply in love, their bond carved into their very bones. The coldness and tenderness, the disguises and sincerity of the past, all lead to the two of them being destined for each other.
