The National Day is coming, and the students go home one after another. Ren Chu sent Wang Xinyu home on vacation. He thought that Meng Xibai would not come to see Wang Xinyu off, but after he came, he found out that he was cheated by his cousin, so he had to watch his cousin and Meng Xibai bid farewell at the airport.
On the other side, Lu Wanwan begged Wang Yuyang to help her bring the mannequin home and give him fruit in return. While carrying the model on his back, Wang Yuyang complained that he had to study hard on National Day. He was applying for a project to go abroad, and a strong competitor appeared. Wang Yuyang wanted Lu Wanwan to help him ask Ren Chu to make up lessons for him, but Lu Wanwan flatly refused.
When Lu Wanwan came home, she found that her parents were preparing for the chorus performance. Lu Wanwan planned to help her parents watch the fruit shop while reviewing her homework. An Jiaxian came here suddenly, saw that Lu Wanwan had questions that she didn't know, and offered to help her read the questions. It turned out that since high school, the two have often done problems together, and An Jiaxian is very experienced in tutoring Lu Wanwan. Ren Chu suddenly appeared at the fruit shop, saw An Jiaxian tutoring Lu Wanwan, and directly pointed out that An Jiaxian had a problem with his problem-solving ideas, so he planned to tutor Lu Wanwan himself, and also ensured that Lu Wanwan's final orthopedic exam results would be acceptable. Two points higher than An Jiaxian. The two also made a bet that if Ren Chu lost, they would give An Jiaxian all the scholarships for the whole year.
Because of the bet, Ren Chu watched Lu Wanwan study all the time. Liang Xia came to see Lu Wanwan that day, and Lu's mother asked Liang Xia how she felt about the university and whether Liang Xia was in a relationship. Liang Xia felt very embarrassed. In the end, Lu Wanwan told her mother that Liang Xia was dating An Jia first. Liang Xia solemnly apologized to Lu Wanwan, and Lu Wanwan also said generously that it didn't matter, and the two finally laughed and let go.
Ren Chu and An Jiaxian rushed to Lu Wanwan's house at the same time, and they sat together for breakfast. Knowing that Lu Wanwan was in trouble, Liang Xia planned to take her boyfriend away. Ren Chu and An Jiaxian also felt that the bet was a bit naive, but Ren Chu believed that the bet could be voided, but he couldn't shake hands with An Jiaxian to make peace. In order to effectively counsel Lu Wanwan, Ren Chu cited cases to seek medical treatment, and Lu Wanwan was able to answer them one by one. In his opinion, Lu Wanwan's basic knowledge is still very solid. In order to combine work and rest, Ren Chu took Lu Wanwan to the theater to watch a movie, but in order to improve Lu Wanwan's English level, Ren Chu chose a foreign film without subtitles, but after watching it, Ren Chu asked a few questions , let Lu Wanwan watch the movie again with questions, Lu Wanwan was very distressed.
Liang Xia gave up traveling abroad because of a quarrel with her mother. She asked An Jiaxian if she had any intention to study abroad, and asked An Jiaxian what she thought about her friend's long-distance relationship. Liang Xia dared not live alone at home, so Lu Wanwan, who knew about this, took the initiative to invite Liang Xia to stay at home temporarily.
Lu Wanwan learned from Wang Yuyang that the competitor he thought was Liang Xia, and also knew that Liang Xia was fighting for a place to go abroad for exchange. Lu Wanwan asked Liang Xia only to learn that this matter was arranged by Liang's mother, and she never asked her daughter Liang Xia's wishes. Lu Wanwan thinks that An Jiaxian should be told about this, and An Jiaxian should also be considerate of Liang Xia's final choice.
Lu Wanwan, Liang Xia, An Jiaxian and others cheered for Mother Lu's community chorus competition, Ren Chu also came, An Jiaxian looked hostile towards him, but fortunately Liang Xia took An Jia away first to avoid a war of words.
Although Lu Wanwan is reluctant to let Liang Xia go abroad, she also knows that some people on this planet are destined to leave, and some relationships will gradually become estranged, but just like energy is conserved, there will always be new people in the vacated places. In new relationships, there are always miracles happening in life.
Accepting the vacation, Wang Yuyang picked Lu Wanwan back to school along the way, and helped her bring her things back to school. When Ren Chu met Lu Wanwan who was returning to school by chance, Fan Yi teased Lu Wanwan when she was going to hold hands with Ren Chu to admit their relationship, but Lu Wanwan said that she was not going to fall in love in college, and she had to study hard and try not to fail the course.
