But Tong Wenjie can no longer tolerate Fangyuan’s explanation and tells Fangyuan that she saw him and Chen Jie. They entered the hotel together and asked him why he didn't open the door, indicating that he would never trust Fangyuan again, and the two had a big quarrel. Tong Wenjie left a divorce agreement and rushed back to Zhengzhou alone, refusing to contact Fangyuan. Fangyuan asked Mia about Tong Wenjie's office location in Zhengzhou, and chased to Zhengzhou to beg Tong Wenjie to believe in her for Duoduo's sake. However, Tong Wenjie said that the two would never go back to the past, and was determined to divorce, and asked Fangyuan to do so. Hide it from Duoduo. Fangyuan and Tong Wenjie calmed down in Beijing and Zhengzhou, and slowly began to adapt to the days without each other. Fangyuan tried to contact Tong Wenjie countless times, but could not get through Tong Wenjie's mobile phone. He was very decadent at home alone. Tina's uncle was at home again smoking cigarettes and refusing to admit his fault with a playful smile. Zhang Liangzhong left home in anger. In order to thank Jiani, Zhang Liangzhong bought Jiani a brand-name bag as a thank you gift. Jiani did not accept it, so Zhang Liangzhong had to invite Jiani to eat alone, but Jiani mistakenly thought it was a dinner party for three families. Tong Wenjie's Zhengzhou team's performance is good, and the work is getting easier and easier. Fangyuan wants to video chat with Duoduo, but it's a little awkward that they haven't seen each other for a month. Fangyuan lets her eat, and Tong Wenjie agrees to eat at home. Tong Wenjie and Fangyuan pretended to be affectionate in front of the computer screen and had a video chat with Duoduo. Duoduo said that she would celebrate their wedding with them after graduation. After the video, Fangyuan wanted to keep Tong Wenjie at home, but Tong Wenjie insisted on leaving, so Fangyuan had no choice but to send her downstairs. After Fangyuan and his wife went downstairs, they saw a snowman in the community, and they felt sad after seeing the thing. They were very sad when talking about the past. Fangyuan couldn't help but confide her feelings to Tong Wenjie again, and wanted to ask for Tong Wenjie's forgiveness, but Tong Wenjie said that they could never go back to the past, and the past was past, and advised Fangyuan to give up. After Tong Wenjie left, Fangyuan sent a message telling her that no matter how far she went, he would be waiting for her at home. Fangyuan and Zhang Liangzhong were drinking together. Zhang Liangzhong advised Fangyuan to remarry Tong Wenjie as soon as possible, but Fangyuan felt that remarriage was a very difficult thing. Tong Wenjie came home again. Jiani, who didn't know the truth, insisted on calling her to her home for dinner, and asked her to call Fang Yuan over too. Tong Wenjie felt very sad when she saw the happy Jiani family. The more she ate, the more uncomfortable she felt. When Tong Wenjie returned home, she felt strange looking at everything at home. It was New Year's Eve, and Fang Yuan invited her to have a New Year's Eve dinner at Fang's father's and Fang's mother's house. The family chatted with Duoduo via video together, and they seemed very happy.
