Lu Hui (Stephy Tang) suffers from pancreatic cancer, which is a big blow to herself and her cohabiting boyfriend Enming (Shawn Yue). Lu Hui's sister loves to read ghost stories and is criticized by the teacher at school. Lu Hui, who is in a bad mood, looks at her ignorant sister and gets angry. Enming comforts Lu Hui's emotions while coping with heavy work. Enming, who encountered layoffs in the company, met Zhu Fangting, an elementary school classmate again during the interview for a new job. Although Enming still took out all his spare time to accompany Lu Hui, Lu Hui, who was tortured by the disease, forced a smile, was emotionally unstable, and behaved strangely, which brought great pressure to Enming. Zhu Fangting's understanding and ease made Enming unconsciously approach her. The two had a relationship and continued without telling Lu Hui. One rainy night, Lu Hui disappeared. Enming encountered a car accident while driving to look for her. He suddenly had the idea of going to Fangting's house to look for her and found that Fangting was injured and had a strange expression. Lu Hui returned home late at night and was soaked all over. In the following days, her body would emit a foul smell. Enming suspected that he and Lu Hui were ghosts, but the development of things was beyond everyone's expectations.
