Episode 20 recap: Wan Xia stepped out of her comfort zone, and Xu Xiaoqian couldn't adapt.

Wan Xia valued the dining ritual. During breakfast, Xu Xiaoqian deliberately chewed loudly, trying to get Wan Xia's attention. Wan Xia asked when they got a dog at home. Xu Xiaoqian earnestly complimented Wan Xia's cooking, saying that if it weren't for their recent weight loss efforts, they would have cleaned their plate completely.

Wan Xia hummed in response without saying anything. When Wan Xia saw Xu Xiaoqian placing used tissues on the dining table, she expressed her difficulty in accepting it. Xu Xiaoqian explained that the tissue could be reused later to save paper. Wan Xia suppressed her anger and let Xu Xiaoqian eat by themselves. Xu Xiaoqian felt that dealing with Wan Xia was really difficult.

Wan Xia considered herself unlucky to have a roommate like Xu Xiaoqian. Xu Xiaoqian didn't put the toilet seat down when flushing, which Wan Xia found hard to accept. Wan Xia confronted Xu Xiaoqian about it, but Xu Xiaoqian pretended not to hear and annoyed Wan Xia. Wan Xia continued to persist, and eventually, Xu Xiaoqian flushed the toilet again.

While Wan Xia was talking to Zhang Yuan, Xu Xiaoqian came out of the restroom. Wan Xia mentioned that Xu Xiaoqian didn't wash their hands after using the toilet, but Xu Xiaoqian stubbornly claimed to have washed them. Wan Xia insisted on proof, and the two nearly came to blows. Zhang Yuan quickly intervened and stopped Wan Xia, saying it wasn't necessary. Xu Xiaoqian, seeing how serious Wan Xia was, admitted that they hadn't washed their hands.

Wan Xia expressed that it was unsanitary to drink tea without washing hands, and Zhang Yuan also took issue with Xu Xiaoqian's failure to wash hands. Pei Zhi Jie also thought that Xu Xiaoqian's behavior of not washing hands after using the restroom was unacceptable. Xu Xiaoqian told Pei Zhi Jie that they were also unreasonable at home and didn't have any freedom.

Wang Bo felt a bit sorry for Xu Xiaoqian, while Lu Zhi Fei said, "Sour tofu in brine." Xu Xiaoqian claimed that they would make Wan Xia change within a week. Xu Xiaoqian apologized to Wan Xia, but Wan Xia refused to communicate with Xu Xiaoqian. Xu Xiaoqian kept pestering Wan Xia, who eventually agreed to sit down and talk. Xu Xiaoqian told Wan Xia that they were ill, and their illness was not light. They demanded this and that every day and found fault with everything. Wan Xia felt that Xu Xiaoqian was simply bullying others and believed that Xu Xiaoqian was also someone with issues who repeated the same things every day. Xu Xiaoqian was caught in self-reflection by Wan Xia's words.

After Wan Xia left, Xu Xiaoqian realized that they had been trapped by Wan Xia as well. Xu Xiaoqian admitted that they weren't a professional doctor and decided to find a professional mental health specialist to examine whether Wan Xia had an illness or not. Aunt Hua, looking at the people in the shop, felt that something was strange, as if someone had an illness. The person Xu Xiaoqian found turned out to be a hairstylist. As Wan Xia listened to what this person had to say, they felt that the person themselves was also mentally unstable. The hairstylist even gave Wan Xia a ticket, and Wan Xia asked Xu Xiaoqian where they found this mentally ill person.

Xu Xiaoqian didn't dare to say anything. As Wan Xia listened to Xu Xiaoqian constantly pushing them to break out of their comfort zone, they believed that Xu Xiaoqian was the one with the illness and wanted to kick Xu Xiaoqian out. Pei Zhi Jie couldn't bear to see this and quickly stopped Wan Xia, while Xu Xiaoqian claimed that they had made a bet with others that they would make Wan Xia change within a week.

Hearing this, Wan Xia felt even more inclined to beat up Xu Xiaoqian. Wan Xia was annoyed by Xu Xiaoqian's presence and expressed a strong refusal to be alone with them. Both Wan Xia and Xu Xiaoqian remained silent. Wan Xia suppressed their frustration with Xu Xiaoqian's bad habits and started exhibiting the exact same bad traits as Xu Xiaoqian.

Xu Xiaoqian was delighted, and Pei Zhi Jie asked them to explain the reason behind their behavior. Xu Xiaoqian happily refused to tell them. Feeling hungry, Xu Xiaoqian noticed that Wan Xia wasn't cooking at all and claimed to have a headache. Xu Xiaoqian started cooking early, and Wan Xia watched as Xu Xiaoqian imitated their own bad behavior. Xu Xiaoqian felt that Wan Xia hadn't considered their feelings and said that it was good for Wan Xia to step out of their comfort zone. Xu Xiaoqian realized that Wan Xia was deceiving them when they divided the cleaning chores, as Xu Xiaoqian had already developed the habit of doing it. This made their senior brothers suffer greatly.

Seeing Xu Xiaoqian enjoying their training, Wan Xia felt a sense of disaster and amusement.
