Gu Renqi (played by Liu Yihao) suffers from mysophobia because of the tragic experience in his childhood, and his personality is also very withdrawn. Although Shuangjiao (played by Shen Yue) grew up in a happy family, she fell into despair because of the unfortunate death of her mother. The two are in a cleaning company in a superior-subordinate relationship. As they get to know each other better, the two scarred hearts begin to get closer to each other and warm each other. With the encouragement and company of Gu Renqi, Shuangjiao gradually began to accept her mother's departure and face up to this destined incompleteness. But at this juncture, Shuangjiao was shocked to learn that her mother's death was not an accident but a man-made disaster, and the culprit behind it was most likely Gu Renqi's grandfather. Under the condemnation and torture of his conscience, Gu Renqi took the initiative to break up.
