A month ago, Xi Shuang disappeared suddenly. Qian Mo didn't know where she went or what happened to her, but after she came back, she became disgusting. She became the lover of Xia Danyang's father, and also became a couple with Zhou Weizhen, whom Qian Mo hated. She always did things to hurt Qian Mo behind his back, but when Xia Danyang found out that the initiator of all the conspiracies was Xi Shuang, Qian Mo didn't want to believe it. She always numbly told herself that she was a child with night blindness, and she couldn't see anything in the dark, which also included Xi Shuang's fault. However, what changed Xi Shuang, the bitter youth, what can we change?
