Episode 12 recap: Lu Xiao Lu and Bai Lan are working hard together to go to Shanghai.

Lu Xiao Lu's mother invited Bai Lan to have a meal and started talking about how she wanted to leave herself after falling in love, and asked Bai Lan if she knew what was going on. Lu Xiao Lu heard that Li Guang Nan had some trouble, so he rushed over to see, only to find that Hu Laoda saw Lu Da Jiang in trouble and started causing trouble, and even asked Lu Xiao Lu to crawl under his crotch! Lu Xiao Lu apologized to Bai Lan for skipping class and explained that he wanted to go to Shanghai with her, but he couldn't ignore Li Guang Nan's situation!

Lu Xiao Lu, accompanied by Bai Lan, Li Guang Nan with Qin Juan, and Chang Jiao with Niu Xiao Ying, celebrated the New Year together. Everyone cared about each other's New Year's wishes. Li Guang Nan was happy that he pursued Qin Juan, and his New Year's wish became to work hard and make money. Niu Xiao Ying was concerned that she was twenty years old and had never been in a relationship, and Chang Jiao agreed. Niu Xiao Ying didn't want to pay attention to him at all. Lu Xiao Lu took the opportunity to announce that he had decided to go to Shanghai with Bai Lan!

When Lu Xiao Lu's mother found out about Lu Xiao Lu's plan to go to Shanghai, she stayed alone in her room and ignored everyone. Lu Xiao Lu tried to coax his mother with fruit, but it didn't work. Finally, Lu Xiao Lu had no choice but to entrust this task to his father. So, during the night, Lu Xiao Lu's father tried to persuade his mother. Unexpectedly, his mother protected Lu Xiao Lu and said that she could scold her son, but he couldn't. Lu Xiao Lu's father was speechless, and Lu Xiao Lu's mother was worried, afraid that Lu Xiao Lu would be easily taken away by his future daughter-in-law. While worrying, she urged Lu Xiao Lu's father to help her come up with a solution. They spent the whole night restless.

While working in the warehouse, Lu Xiao Lu and Li Guang Nan noticed that Long Jiao seemed to be making noise under a nearby cloth. They quietly approached and discovered that Long Jiao was hiding inside, holding a book. Then they heard someone looking for Long Jiao. Lu Xiao Lu and Li Guang Nan quickly covered Long Jiao and went to deal with those two people. The two people started complaining that Long Jiao wasn't working and that no one was repairing the equipment. Lu Xiao Lu and Li Guang Nan began to cover for Long Jiao, saying that he might be slacking off somewhere. If they found him, they should call him back. After hearing this, the two people left.

Li Guang Nan and Lu Xiao Lu turned around and released Long Jiao. They asked him why he was reading a high school chemistry book. Long Jiao explained that the factory's performance was not good, so he wanted to take the adult college entrance examination. Li Guang Nan didn't approve of it, but Lu Xiao Lu thought it was a good thing.

Lu Xiao Lu's mother invited Bai Lan to have a meal and started talking about Lu Xiao Lu's plan to go to Shanghai, expressing her dissatisfaction with the decision and suggesting that they would regret it in the future. Bai Lan, however, said that it's better to be a little crazy when you're young, or else you'll regret it later.

Meanwhile, Li Guang Nan accompanied Qin Juan to see a new house. Qin Juan remarked on how the city was getting better, but Li Guang Nan was puzzled about why Lu Xiao Lu wanted to leave. Qin Juan mentioned that Bai Lan didn't like it there. Qin Juan also praised Lu Xiao Lu for being loyal to his friends and said that he would never let them be bullied. This gave Li Guang Nan an idea because Lu Xiao Lu wouldn't abandon his friends.

Shortly after, Lu Xiao Lu received news about Li Guang Nan getting into trouble. Lu Xiao Lu immediately rushed over and found out that it was because of Hu Laoda. Lu Xiao Lu decided to go in alone while asking Chang Jiao and Niu Xiao Ying to wait outside. Hu Laoda started to harass Lu Xiao Lu, but Lu Xiao Lu gave a signal, and smoke bombs were thrown inside, creating a distraction. Lu Xiao Lu took the opportunity to protect Li Guang Nan and run out.

Later, the group gathered for a meal. Li Guang Nan kept implying to Lu Xiao Lu that they shouldn't leave him alone. He even suggested that Lu Xiao Lu should open a milk tea shop with him and offered money as an incentive. Lu Xiao Lu agreed to the idea. Afterward, Lu Xiao Lu and the others became busy researching about milk tea, causing Lu Xiao Lu to neglect his studies. Bai Lan became suspicious and Chang Jiao made up an excuse that Lu Xiao Lu's mother was sick. Bai Lan went to visit Lu Xiao Lu's home, and despite Lu Xiao Lu's efforts to hide it, Bai Lan discovered the truth. Bai Lan asked if Lu Xiao Lu didn't want to study properly, and Lu Xiao Lu honestly said that he couldn't ignore Li Guang Nan's situation.

To Lu Xiao Lu's surprise, he soon found out that Li Guang Nan had been deceiving him. Li Guang Nan admitted that he had to resort to that in order to keep Lu Xiao Lu from leaving. They had a big fight, and after that, Lu Xiao Lu focused on his studies. He went out for a Western meal with Bai Lan and their classmates but felt out of place, so he made an excuse to leave. Bai Lan noticed and followed him. They ended up eating fish ball soup together. Bai Lan expressed concern that Lu Xiao Lu might have a hard time adapting to being away from his friends and family, but Lu Xiao Lu insisted that it was his own choice.

Lu Xiao Lu then mentioned the news about Li Guang Nan's trouble. At first, he thought it was fake, but later discovered that it was Tao Jie, Lu Da Jiang's old lover. Lu Xiao Lu quickly became friendly with Tao Jie and learned about their love story. Eventually, Tao Jie decided to give the beverage contract of the dance hall to Lu Xiao Lu and Li Guang Nan. Lu Xiao Lu and Li Guang Nan reconciled after getting drunk together.
