The two-way journey and redemption of the young general guarding the border (Tiansha Lone Star) and the gentle killer (the tool of the dark organization).
A shipwreck threw two strangers to the same island. In order to survive, they depend on each other. He cut down trees to build a shed, while she looked for water and food; he made a fire to keep out the cold, and she healed her wounds and detoxified her. In the wind and waves on the isolated island, he talked about the scenery of the border area, and she hummed a Jiangnan tune. Two hearts quietly come closer. He made a promise: "If I can leave, I will marry you!"
However, as fate would have it, they were eventually separated.
Six years later, an imperial decree came. The queen's cousin Liu Zhiwei became his fourth wife. On their wedding night, he recognized the bride from her sharp-jointed hands. She suffered under disguise, entered the government as a substitute for a wife, was poisoned, and was responsible for the assassination mission of the organization. In the deep courtyard, there is an undercurrent. Can she hide her identity? Can he protect her?
Intention: When I meet you, I am no longer alone.
