The Science of Falling in Love – Wu Jiayi, Liu Yichang

Su Chengcheng is studying at Southeast University of Science and Technology, which is a science and engineering university. The male students there are all in pairs. When a male student confesses to a female student, the gift they give is actually a hammer.

In her sophomore year, she planned to have a good relationship and participated in the school's social activities. As a result, she met a clumsy and awkward straight man who almost burned her roommate Li Meizi's skirt. Just when she finally met a normal guy, he was quickly snatched away by other girls. Su Chengcheng felt hopeless about being single.

One morning, she was riding her bike to class and the chain fell off halfway. Xiao Yuhe, who was riding an electric bike, picked up the chain and gave it back to her. Su Chengcheng fell in love with him at first sight. During course selection, Su Chengcheng was pushed down by the surging crowd, and it was also Xiao Yuhe who helped her up. At night in the bookstore, she coincidentally found Xiao Yuhe's student card for the third time. Su Chengcheng felt that this was a fateful encounter, so she decided to confess to him.

Xiao Yuhe, in his childhood, was called Zhu Panpan and transferred to the elementary school where Su Chengcheng was studying. Although he had good grades, he was very introverted. The teacher urged everyone to be friends with Zhu Panpan, but it made him very uncomfortable. Su Chengcheng said that some people just don't like to make friends, so don't force him. The two became friends because of this. Su Chengcheng shared shaved ice with him and said they would go to high school and college together and be together forever. During the Children's Day performance, the sound of a balloon being accidentally popped scared Zhu Panpan and he froze on stage. His mother took him home and forced him to pop a room full of balloons, leaving him with deep psychological trauma. When asked later, Su Chengcheng said she had no other childhood friends. Xiao Yuhe put a brainwave testing device on her to prove that she liked him. This conversation was overheard by the dean, Chen Xiaorong, who encouraged them to do a love-proof experiment.

Su Chengcheng specially changed into an uncomfortable but beautiful dress to attend Xiao Yuhe's appointment. Xiao Yuhe rode an electric bike, and Su Chengcheng was very happy sitting on the back seat. Xiao Yuhe deliberately rode over the speed bump, making Su Chengcheng feel very uncomfortable. When they arrived at the amusement park, Xiao Yuhe insisted on taking the timid Su Chengcheng into the haunted house, saying that the bridge effect could be better tested. Su Chengcheng was persuaded, but Xiao Yuhe quickly disappeared. Su Chengcheng was scared and cried, and when she saw Xiao Yuhe, she hugged him tightly. After coming out of the haunted house, Su Chengcheng lost her mood. Xiao Yuhe said that the experiment was not over and took her to play real-life CS. Originally, the two were on the same team, but Xiao Yuhe caught Su Chengcheng and made her clothes strap break. When they returned, Xiao Yuhe did not forget to ask Su Chengcheng to complete the experimental data. Su Chengcheng felt that she was being used by him to do experiments and was very sad.

During breakfast, Su Chengcheng grabbed the last basket of Xiaolongbao and ran into Xiao Yuhe who also wanted to buy Xiaolongbao. Su Chengcheng remembered that she had accidentally charged him an extra 3.5 yuan in a transfer the night before, so she gave him the Xiaolongbao. The two argued and Su Chengcheng didn't want to see Xiao Yuhe, so she asked Zhu Jiafa to help her ask for leave. However, Du Zhuanjia did not approve Su Chengcheng's leave and asked her to come to the laboratory. Zhu Jiafa used Xiao Yuhe's phone to send a WeChat message to Su Chengcheng, but found out that he had been blocked. Zhang Xixi's ex-boyfriend came to ask for a reconciliation, saying that he didn't know which girl had poured milk tea on him. Zhang Xixi pretended to be cold and ignored the scumbag, but was actually very upset in private. She forgot her phone and card on the bus, but luckily Gu Chen appeared and gave her two coins. During the lab class, Zhang Xixi met Gu Chen. After class, Zhang Xixi stopped him and returned the coins to Gu Chen.

During the exam, a classmate asked Su Chengcheng for the answers, but she said she didn't know and was caught by Xiao Yuhe. Afraid that her grades would be cancelled, Su Chengcheng went to find Xiao Yuhe, but he was accidentally knocked down by a few boys playing basketball and fell into a large trash can. Su Chengcheng quickly took out her phone and recorded it, and even turned it into a funny video when she got back to the dorm. She accidentally sent it to the lab group, and although she quickly retracted it, the video still spread. In order to stay in the lab, Su Chengcheng dyed her hair back and asked for help from Zhu Jiafa. Zhu Jiafa promised to help her campaign, but asked for Xiao Yuhe's funny video in return. Liu Dongmao asked Su Chengcheng to collect data in the monkey room, but her key was taken by a monkey named Jianming, causing chaos in the monkey room. Zhao Yiran, who was in charge of the monkey room, was very angry and even annoyed the expert Du.

Expert Du organized a vote to decide Su Chengcheng's fate. In the end, the vote was tied, but Xiao Yuhe, who arrived late, cast the final vote in favor of Su Chengcheng. Happy Su Chengcheng and her dormitory sisters went to KTV to celebrate. She believed that Xiao Yuhe's vote was for the sake of the experiment, to verify that he was removed from the blacklist. Xiao Yuhe replied that it was not the case, and Su Chengcheng couldn't figure out his thoughts. Gu Chen ran into Zhang Xixi's ex-boyfriend and his new girlfriend. He took the opportunity to thank them and spilled milk tea on the ex-boyfriend, avenging Zhang Xixi. Later, Zhang Xixi, who was dressed casually at home, went downstairs to pick up takeout and ran into Gu Chen, feeling embarrassed and running away. Gu Chen thought Zhang Xixi was a bit cute in a contrasting way.

The Brain and Intelligence Laboratory and Gu Chen's laboratory have clinical cooperation with the hospital. Everyone went to the hospital. An old paralyzed grandfather successfully stood up and walked with the help of an exoskeleton and could even do some daily activities. Xiao Yuhe, as a representative, accepted an interview, and Su Chengcheng was very impressed. During the National Day holiday, Su Chengcheng wanted to go out and play with her roommates, but they all had their own things to do, so Su Chengcheng stayed alone in the dormitory. Su Chengcheng's father came to see her, along with her stepmother and younger brother. Su Chengcheng led the three of them to visit the school, and Su's father suggested taking a family photo. Su Chengcheng was about to step forward for the photo, but Su's father gave her the phone to take the picture. The stepmother took Su Chengcheng to buy shoes and said that Su's father had always missed her. However, even the chance encounter of Xiao Yuhe at the dinner table knew that Su Chengcheng did not eat cilantro, but Su's father forgot. Later, he also forgot what grade Su Chengcheng was in.

Su Chengcheng was walking on the road when a speeding bicycle knocked her down and scraped her arm. Xiao Yuhe passed by and took her to the school hospital. They chatted and Xiao Yuhe took Su Chengcheng to the school gate to take pictures, fulfilling her regret. On Mid-Autumn Festival, Xiao Yuhe was feeling down, so Su Chengcheng took him to her secret base - the mountaintop - to enjoy the scenery. Su Chengcheng made paper airplanes to cheer up Xiao Yuhe, and Xiao Yuhe used his phone to give Su Chengcheng a picture of the moon. During the holiday, each roommate had their own troubles. Xie Xiaomeng worried about the money for her brother's tutoring classes, Lin Ying's brother seemed to have an unhappy past, and Li Meizi was scolded by her father for playing on her phone, causing an argument and an early return to the dormitory. The caretaker was not around, so Jianming became angry and broke out of his cage, leaving everyone in the laboratory helpless.

In the love experiment, Su Chengcheng gathered her courage and hugged him, and their heart rates accelerated. At this moment, Gu Chen came to look for Su Chengcheng, and the two went to a clothing store where they finally found a wrongly sized piece of clothing. However, now Su Chengcheng had to use the money she had saved for an electric bike to buy it. Xiao Yuhe went to a CD store and met Lin You. He told her that she didn't need to buy CDs for him anymore and left.

On his way back to school, Xiao Yuhe passed by and saw Su Chengcheng helping Gu Chen try on clothes through the shop window, and he became jealous. Su Chengcheng brought Gu Chen back to the laboratory, where Zhang Xixi was puzzled about why she had been seeing Gu Chen so often. Gu Chen told her that he had asked her to go to the rooftop, and the love experiment began. To help Su Chengcheng and Xiao Yuhe, Zhu Jiafa left the two of them to pick up the takeout alone. Su Chengcheng took the opportunity to give Xiao Yuhe his clothes, but the jealous Xiao Yuhe accidentally knocked the clothes onto the ground. Misunderstanding Su Chengcheng, who then left with the heavy takeout, she accidentally twisted her foot while climbing the stairs, and Xiao Yuhe carried her up the stairs on his back.

There was a love research sharing session with many students and teachers attending. During Xiao Yuhe's presentation, his computer encountered a problem, causing Su Chengcheng's favorite page on the PPT to be stuck there. Su Chengcheng thought that Xiao Yuhe was humiliating her, so she stood up and said that he was self-righteous. The scene was awkward, and the expert Du was very angry, saying that if Su Chengcheng could not pass the midterm assessment, she would be expelled. In order for Su Chengcheng to stay, Xiao Yuhe fought for the task of running data. With a tight deadline and heavy workload, Su Chengcheng had to stay up all night to run the data. She thought that Xiao Yuhe was making things difficult for her, so in anger, she threw away his dyed coat. Su Chengcheng fell asleep while running data, and Xiao Yuhe helped her finish the task, passing Du's assessment.
