In an unexpected encounter, Lin Xinran met Qi Di. The two gradually got to know each other and entered each other's world. Qi Di looks exactly the same as Lin Jingze, a young boy who disappeared after spending four years with Lin Xinran day and night, but has completely opposite personalities. He is a man who grew up under the eye of his uncle, the indifference of his grandfather, and the absence of his parents. He is used to hiding all his worries and sorrows. After a series of conspiracies were uncovered, Lin Xinran learned Qi Di's true identity. It turned out that he was not the boy who lost his memory and was rescued by the Lin family, but his twin brother. Misunderstandings and choices came one after another, and Lin Xinran didn't know if she could still trust him and stay by his side as always. But in the end, I finally understood that he, Qi Di and Qi Zhuo, the ones left behind and those who died, have different personalities, but they are actually the same tolerant and kind-hearted people, but the living people always have to bear more.
