Episode 4 recap: Yang Shang Wei's sister requested an upgrade when she was flying.

A little girl's mother was waiting with her to board a plane. It was the girl's first time flying alone, so her mother entrusted her to the care of a flight attendant. Wing happened to be the flight attendant on this plane, so she took the little girl to the restroom. To their surprise, the little girl had a small pet in her backpack, which she had been carrying on her back all along.

When Chen Jie passed by, she noticed that there seemed to be something moving in the little girl's backpack. She informed the staff, and they quickly went to handle the situation. The little girl admitted that she wanted to bring her pet with her to Canada because there would be no one to take care of it otherwise. Some people actually noticed that Fang Ke Er had feelings for Yang Shang Wei, so they discreetly reminded her from the side. These were all things that Yang Shang Wei's good friends had said, but they were said in a veiled manner, and Fang Ke Er still didn't understand.

The little girl insisted on bringing the pet on the plane, but Zhang Ruo Ling came over to persuade her after learning about it. After Zhang Ruo Ling's persuasion, the little girl finally felt at ease. Chen Jie called Lv Zhi Shan, but Lv Zhi Shan didn't know how to answer because she had consulted a lawyer and learned that her current conditions were indeed not as good as her ex-husband's. It was very likely that her daughter would be awarded to her ex-husband. Thinking about this, Lv Zhi Shan felt inexplicably sad.

After all, she could give up everything, but she still just wanted her daughter. While Yang Shang Wei was at work, Fang Ke Er still cared about him. Yang Shang Wei deliberately asked if anyone had talked to her, but Fang Ke Er didn't take the words to heart and left naturally.

Chen Jie still cared about Lv Zhi Shan, but Lv Zhi Shan had no appetite to eat. The question she was most concerned about now was how to regain custody of her daughter. The only solution she could think of now was to resign, but everyone was unwilling to let Lv Zhi Shan quit her job. They all came over to persuade her.

Yang Shang Wei also understood Lv Zhi Shan, but Chen Jie felt that Yang Shang Wei's presence was not helpful and instead believed that Lv Zhi Shan should strive for custody while keeping her job. In fact, they had met on the first day of work eleven years ago and had been very good colleagues ever since.

When Yang Shang Wei took the company bus, he encountered Fang Ke Er. The buses at Hong Kong Airport are all self-driving and can be considered at the forefront of the entire airport. Fang Ke Er mentioned that she received a batch of new students' emails a couple of days ago, and she needed Yang Shang Wei to review them. However, Yang Shang Wei didn't care at all and was busy taking pictures of the scenery around with his phone.

A woman named Yang arrived to take a flight and immediately demanded an upgrade from the staff. Naturally, they refused according to the regulations. However, she then mentioned having relatives who work for the airline and wanted to use that connection to help with the upgrade. It was only when Zhang Ruo Ling arrived that she realized the woman was actually Yang Shang Wei's sister. Faced with Yang Shang Wei's sister, she could only use her own connections to assist.

Although Zhang Ruo Ling has divorced Yang Shang Wei, it seems that she is still willing to help with matters concerning their family. Yang Shang Wei's sister hasn't come back for a long time, but for her, these things are not a big deal. On the other hand, Chen Jie suggested that Lv Zhi Shan could bring her daughter to the airport kindergarten, which would make it easier to take care of her. In fact, she didn't want Lv Zhi Shan to quit her job either because she also loves her work. Just then, a passenger lost something, and Lv Zhi Shan hurried to handle it. The girl was very anxious because she had lost her identification documents, and there were still two and a half hours before the flight took off. Lv Zhi Shan would do her best to help.

Guo Qi Guang found Wing and even mentioned that her sister Zhang Ruo Ling doesn't like hotpot but prefers spicy hot pot. In fact, Wing deliberately told him the wrong information to ensure that he would have no chance to pursue Zhang Ruo Ling. After all, she believed that Zhang Ruo Ling and Yang Shang Wei were the perfect match.

Originally, Yang Shang Wei was supposed to drive Zhang Ruo Ling, who was exercising, back home, but she refused. Yang Shang Wei intentionally mentioned Zhang Ruo Ling's food preferences and encouraged Guo Qi Guang to pursue her.
