Ren Chu went shopping with his cousin Wang Xinyu, and because Meng Xibai liked quiet girls, Wang Xinyu decided to change for him. Ren Chu asked her cousin what she would think if she kissed someone she knew. Wang Xinyu thought that her cousin was talking about kissing Meng Xibai, so she was naturally very happy to be Meng Xibai's girlfriend. This made Ren Chu think that being able to kiss meant that the two were already together.
Ren Chu dressed up and went to meet Lu Wanwan. Seeing that, he took away the thermos cup from Lu Wanwan's hand in a moment of excitement. Lu Wanwan was also very embarrassed about the kiss, and pulled Qiaoqiao away quickly. Lu Wanwan and Qiaoqiao were in class, and Ren Chu came to ask the students by the window to pass the thermos to Lu Wanwan. Guan Ai just happened to meet Ren Chu, and chatted with Ren Chu, and the students in the class quickly started gossiping The gossip about the school girl and school grass was revealed.
Lu Wanwan and Wang Yuyang had dinner together. Lu Wanwan thought that Ren Chu was troubled, so when Wang Yuyang asked about it, he recounted the incident of the two kissing when they were eating chicken in CS last time. Wang Yuyang concluded that Ren Chu liked Lu Wanwan. But Lu Wanwan didn't think so, because Ren Chu kissed herself abruptly without formal confession. This was her first kiss, which made Lu Wanwan feel aggrieved. Lu Wanwan lamented that her love life was bumpy. She had a crush on An Jia before and ended in failure, and then she also failed in trying to chase Wang Yuyang. She already considers herself to be a male girlfriend.
Lu Wanwan practiced intravenous injection skills alone in the baking club, but she was also afraid of pain, so she pricked herself again and again and screamed. The members of the swimming team knew that Ren Chu had applied for a graduate student at Pingda University, and he was very reluctant to leave the school. Ren Chu learned that a team member had just had a girlfriend, and asked him about his skills in courting girls.
Lu Wanwan still couldn't learn venipuncture, so she simply came to her senior Meng Xibai for advice. Meng Xibai asked her to recruit volunteers. Pricking acquaintances would make her nervous, but unfamiliar volunteers would make her feel responsible. Meng Xibai told Lu Wanwan not to experiment with Ren Chu, after all, it would hurt her to tie her boyfriend. Lu Wanwan only found out that Ren Chu had verbally admitted that she and she were boyfriend and girlfriend, which made her very angry.
Lu Wanwan came to the swimming pool to look for Ren Chu, and happened to see the members of the swimming team talking about how to pursue girls. Lu Wanwan angrily called Ren Chu away and asked him why he told the senior that he and she were boyfriend and girlfriend, and she thought Before Ren Chu kissed himself just to tease her, it was impossible for Ren Chu to like herself, because they were people from two worlds.
Wang Xinyu wanted to stay with Meng Xibai in the laboratory, but Meng Xibai thought that Wang Xinyu's stay in the laboratory would affect him, and wanted her to leave quickly. Ren Chu came to take his cousin away after learning about it, and persuaded Wang Xinyu to consider things from Meng Xibai's point of view. After all, Meng Xibai needs to concentrate on studying medicine, and he will naturally arrange a date when he is finished.
Ren Chu signed up for Lu Wanwan's venipuncture volunteer, and now there is only one volunteer. In order to practice well, Lu Wanwan had to agree to use Ren Chu to practice venipuncture. But Lu Wanwan punctured several times, but she made mistakes because of nervousness. Ren Chu asked Lu Wanwan to take the needle injection as an exam and encouraged Lu Wanwan to do it next time. Encouraged by Ren Chu, Lu Wanwan finally managed to learn venipuncture. To thank Ren Chu, she agreed to make dessert for him.
During the exam in class, Lu Wanwan succeeded in venipuncture for the first time this time, which made Qiaoqiao feel incredible. Meng Xibai's first date with Wang Xinyu even took her to the lake to fish. Wang Xinyu was so bored that she fell asleep. Meng Xibai accidentally found that Wang Xinyu was bitten by a mosquito and helped her apply ointment. Wang Xinyu liked Meng Xibai's thoughtfulness very much. Bai also took the opportunity to let Wang Xinyu keep his original appearance, there is no need to become quiet for him.
Lu Wanwan realized that yelling at Ren Chu before was a bit unqualified, but she was too embarrassed to apologize in person, so she wrote a post-it note and planned to secretly put it in the locker of Ren Chu's swimming room, but she was caught by Ren Chu on the spot arrive. Lu Wanwan said that he and Ren Chu should be ordinary friends in the future, and Ren Chu also asked Lu Wanwan to forget the kiss. But Ren Chu also hoped that the relationship between the two would follow the steps that Lu Wanwan expected, and sooner or later, she would like him.
