Episode 7 recap: Former Tang Rui Ze returned to his home country in a grand manner.

Su Qing Che searched for ways to please girls and his teammates eagerly offered suggestions. This time, Tang Rui Ze came to the university as a professor in the field of new media and economics and unexpectedly ran into Qian Cheng. Qian Cheng accidentally referred to him as her "former" and immediately corrected herself by calling him "uncle."

When Song Xing Chen discovered that the back of her dress couldn't be zipped up during a fitting, she specifically asked Su Qing Che for help and took the opportunity to confess her feelings to him. Tang Rui Ze remembered that Song Xing Chen was allergic to mangoes and instructed the waiter not to include mangoes. However, Song Xing Chen explained that her mango allergy had disappeared over time.

Former Tang Rui Ze returned to his home country, and Han Xiao Li spotted Lu Qun at a nightclub with another woman. She felt that he was flirting with her while being involved with other women, so she immediately came up with a plan against him. Su Qing Che contacted Lu Qun late at night because of Song Xing Chen's behavior, wanting to confirm if his phone was broken. He found out that it wasn't broken, Song Xing Chen simply wasn't contacting him. He didn't know what to do and discovered online that this was a situation where a girl didn't want to interact with him. Feeling helpless, he decided to give her space.

The next day, because theft incidents frequently occurred in the neighboring community, the rescue team needed to provide safety knowledge to the elderly. However, the elderly misunderstood and thought they would have to spend money on installing security devices, so they were resistant. Lu Qun patiently provided them with safety knowledge, using gestures to explain alongside their explanations due to the hearing problems of the elderly. Their patience won the aunties' favor, and they all joined a matchmaking group.

Qian Cheng was about to attend a class taught by a teacher transferred from an Ivy League university. When she arrived in the classroom, she was surprised to find that the teacher was Song Xing Chen's ex-boyfriend, Tang Rui Ze. She directly called him "uncle," causing even more astonishment. Tang Rui Ze learned from others that Qian Cheng's academic performance was extremely poor, so he planned to teach her a lesson.

Su Qing Che confessed his feelings to Yang Xiang but was directly rejected by her because he was overly concerned about her. Listening to Lu Qun's approach in pursuing someone, Su Qing Che became angry and wanted to confront him. Lu Qun took the opportunity to impart his techniques for wooing someone, and Su Qing Che's attention shifted entirely to Lu Qun's advice.

There was a batch of vaccines from the Red Cross that needed to be transferred, and Lu Qun was tasked with handling the matter. Su Qing Che learned from his social media feed that Song Xing Chen had injured her leg, so he hurriedly bought medicine for her and carried her to the couch. He gently applied the medicine to her and took over all her work.

Song Xing Chen received a notice from her alma mater about the school anniversary celebration. In order to attend the event, she bought new clothes. In an attempt to avoid dressing too revealingly, she deliberately chose a conservative outfit, but Song Xing Chen rejected all of her choices in the end.

At the school anniversary celebration, Song Xing Chen ran into her ex-boyfriend, Tang Rui Ze, in the hallway. Their unexpected encounter happened because Tang Rui Ze found Song Xing Chen's student ID card. This led to their acquaintance and subsequent relationship.

After a brief greeting with Tang Rui Ze, Song Xing Chen hurried alone to the auditorium, with Tang Rui Ze following behind. However, the teachers mistakenly assumed that they were already married. After being separated for several years, Tang Rui Ze was surprised to learn that Song Xing Chen was no longer allergic to mangoes. As they sat down, they reminisced about their time in school and recalled how they had planned to see a play together. However, Tang Rui Ze received a notification from a teacher about further studies, which caused them to part ways after graduation.

Professor Li informed Song Xing Chen that there had been changes regarding her application for a Ph.D. If she wanted to continue applying, she would need to adjust her research direction. Feeling disappointed, Song Xing Chen left the school. Tang Rui Ze noticed that she seemed troubled and offered to accompany her home, but she politely declined. Su Qing Che notified Song Xing Chen about the Red Cross vaccine transportation task and, considering her professional qualifications, she accepted the assignment directly.

The next day, as they were about to depart for the mission, Gao Qing Yin informed Su Qing Che that he needed to go home in a few days and asked him to arrange for someone to pick him up. Su Qing Che delegated this task to Lu Qun. Song Xing Chen was unhappy about her Ph.D. application situation and didn't show much favor toward Su Qing Che. Su Qing Che mistakenly thought that she had developed feelings for someone else.

While on the way to the rescue mission, Tang Rui Ze messaged Song Xing Chen. At the same time, a teammate in the same vehicle deliberately used the intercom to gossip about Song Xing Chen's relationship with Su Qing Che. Su Qing Che, in another vehicle, listened attentively, expecting to hear something else, but was disheartened when he heard the word "friend." Lu Qun comforted him by saying that it was because Song Xing Chen was shy.

The teammates continued to gossip, and other colleagues became curious as well. Song Xing Chen didn't deny her relationship with Su Qing Che but also didn't confirm it. Just as she was about to reveal their true relationship, she noticed that the other person's intercom was still on and immediately understood his intention. She directly refused to answer. Meanwhile, Lu Qun cheered up Su Qing Che as he continued to drive.
