Episode 21 recap: Sang Xia was confessed to with a banner.

Li Ran specially bought groceries and invited Lei Ming and Sang Xia to come over for a meal. While Grandma was still cooking, it was only Lei Ming and Sang Xia left together to chat. Sang Xia even asked Lei Ming if he used to study at this table. Grandma would be happy to see just the two of them. Lei Ming had once carved the character "endure" on the table.

In the administrative building of the school, someone came to the school at night and hung up a banner directly opposite. This incident caused quite a stir in the school. It turned out that someone wanted to pursue a romantic relationship with one of the teachers in the school, so they intentionally made a public confession at the school. Meanwhile, the Chinese language teacher was giving a class, teaching a rather melancholic story, and then asked if anyone had ever been in love. Everyone glanced at each other.

The Chinese language teacher said that they should focus on their patriotic duties until they go to college, and then they can have a proper romantic relationship. The students quickly analyzed privately to figure out who this "xs teacher" could be, and soon narrowed it down to Sang Xia. The teachers were also discussing the matter, and Sang Xia always felt that it might be someone else, but her colleagues believed it was most likely Sang Xia.

Next, they needed to figure out who actually hung up the banner. Everyone now believed it was Sang Xia, and wherever she went, she would be teased by her colleagues. Sang Xia decided to personally check the surveillance footage and was surprised to see Lei Ming's figure in the video. She took a screenshot and went to find Lei Ming.

When Lei Ming saw Sang Xia, he started avoiding her, which felt very strange to Sang Xia. In the evening, when Lei Ming was about to leave on his bike, Sang Xia followed him. They went to a bar together, and Sang Xia thought that Lei Ming was confessing to her. So she made it clear that she didn't like this kind of confession, which left Lei Ming completely confused.

At this point, the thing that troubled Lei Ming the most was the compensation, as there had been a conflict with someone named Zhi, which resulted in Lei Ming having to bear a substantial amount of compensation. Just as they stepped outside, they ran into the Chinese language teacher. Since Lei Ming had been drinking and couldn't ride his bike, the teacher ended up giving them a ride back. In the car, the teacher gossiped and asked if they were in a romantic relationship. After receiving a negative answer, she seemed to breathe a sigh of relief.

The atmosphere in the car was a bit awkward, so the Chinese language teacher played fast-paced music.

The New Year's Day is approaching, and students from other classes have signed up to participate in the New Year's Eve party. The students from Class 11 also wanted to go and watch the performances. It was at this time that Lei Ming told everyone that Cheng Yu Shan had won first place in the math competition. Everyone was thrilled for her.

Lei Ming also added pressure to everyone because they had already reached a score of 500, but to reach 600, they needed to put in more effort. The road ahead would become increasingly challenging. Jiang Qing Lang bought gifts for Cheng Yu Shan with Bian Xiao Xiao. After a while, Jiang Qing Lang also prepared a gift for Bian Xiao Xiao, which made her very happy.

Soon, it was the night before New Year's Eve, and the school held a New Year's Eve party. The students enjoyed it a lot. However, during the intermission, the moral education teacher stood up and told everyone that he had hung up the banner himself. It was Lei Ming who had seen him, and Lei Ming didn't tell the truth to help him.

Sang Xia started to panic because everyone was saying it must have been her. To avoid making the situation awkward, Sang Xia planned to leave quietly. However, just as she was about to leave, she jokingly played along with the idea that the person by his side was her. But the German teacher mentioned another teacher's name, which relieved Sang Xia but also made her feel embarrassed. She could only wish them well and Lei Ming laughed on the side.

Next, when the host announced that the students from Class 11 should come up on stage to perform, everyone in Class 11 was surprised because they hadn't prepared any performance. But at that moment, the music started playing, and Sang Xia realized it was her favorite band. She was extremely happy. They came because Lei Ming used to be a student of the lead singer, who sang Sang Xia's favorite song. Sang Xia was overjoyed.

When all the students finished school, Li Ran and Bian Xiao Xiao saw Jiang Qing Lang leaving with Cheng Yu Shan, and they felt a bit disappointed. Lei Ming went to the bar and found the Chinese language teacher. This time, Lei Ming wanted to borrow money from her. The Chinese language teacher took this opportunity to confess to Lei Ming. Although it seemed like a joke, she was actually serious.

The Chinese language teacher felt sad but also knew that today she was truly saying goodbye to Lei Ming. Jiang Qing Lang initially thought that Cheng Yu Shan also liked him, so he took the opportunity of New Year's Eve to confess to her. However, Cheng Yu Shan revealed that she didn't have romantic feelings for him.

Yu Yang also sent a message to the person he most wanted to wish a Happy New Year, and Sang Xia had initially invited Lei Ming to have dinner together. However, Lei Ming hurriedly ran to take a ride after seeing a message on his phone and ended up not keeping the appointment.
