Before the Chinese Valentine's Day, Li Mei flew from the United States to Sichuan to visit her fiancé Ding Lun, who was working on tourism planning in Yucheng. Unexpectedly, she was treated coldly by Ding Lun, who blamed Li Mei for disturbing him at this time. Li Mei, who was full of grievances, went to Bifeng Gorge to see the pandas alone. When she picked up her mobile phone, she accidentally fell into the Nuwa Pool and sprained her foot, which put her in trouble. Xiao Wei, a trainer at the panda base, volunteered to go find someone who had not come up from the canyon. The rescued Li Mei was angry with Ding Lun and did not want to go back, so she stayed at Xiao Wei's house in the ancient town. Ding Lun finished his report to the review committee and was intercepted by his mother who came from Chengdu as soon as he left the meeting room. Ding's mother blamed him for losing Li Mei, and talked about his marriage with Li Mei while scolding him. Unexpectedly, this aroused Ding Lun's disgust, saying that her mother colluded with Li Mei to force him. Ding's mother saw Xiao Wei sending Li Mei back downstairs from the window, and she had doubts in her heart. Ding Lun's tourism plan was not approved, saying that it lacked the soul of the city. He was in a terrible mood, and the conflict between him and Li Mei clashed again. In order to let both parties think calmly, Li Mei decided to leave Ding Lun for a while and became a volunteer at the panda base. Ding Lun, who was looking for the soul of the city with his female secretary Xiaoya, ran into Xiao Wei carrying Li Mei back to the town on a motorcycle in the ancient town. Xiao Wei's help to Li Mei staying in the hotel was mistaken by Ding Lun as a compromise, so he punched Xiao Wei. This punch knocked out Li Mei's last thought of him. Li Mei's vacation was about to end, and she flew back to the United States to continue her master's degree. Before leaving, she gave Xiao Wei a red bean she picked up under a red bean tree. A few months later, Li Mei, who obtained a master's degree, flew to Yucheng, Sichuan again and met Xiao Wei at the panda base.
