Episode 5 recap: Qian Heng discovered the secret to falling asleep.

When Wu Jun woke up in the morning, he found himself lying in a hotel room and noticed that there were strands of hair on the pillow. After all, he didn't remember anything that happened after getting drunk and returning to the hotel last night. Wu Jun quickly told Qian Heng about this, feeling frustrated that he couldn't remember anything. Upon hearing this, Qian Heng couldn't help but laugh and advised Wu Jun to be nicer to Cheng Yao so that he could find some consolation in his heart.

Cheng Yao saw Wu Jun and Qian Heng play-fighting outside the office and initially thought there might be something wrong with Qian Heng's sexual orientation. Qian Heng's behavior had been quite suspicious lately. Qian Heng jokingly suggested to Wu Jun that he should sit on the toilet for half an hour in the evening to see if he would feel sleepy. However, even after sitting for a full 40 minutes, Wu Jun felt no signs of sleepiness. When Cheng Yao saw him in the living room, she thought he was constipated and put some laxatives in the toilet.

Qian Heng came out not knowing what to say. Cheng Yao felt that Qian Heng had a secret, so she planned to investigate tonight. Otherwise, if Qian Heng couldn't sleep and went out for exercise again, Cheng Yao would secretly follow him. Cheng Yao even had trouble keeping up with Qian Heng, and she ended up sweating profusely. Just when she sat down to rest, unexpectedly, Qian Heng returned and stood in front of her.

Qian Heng warned Cheng Yao to stop all her tracking behavior, leaving Cheng Yao feeling dejected. She said she just wanted to understand Qian Heng better. Qian Heng didn't say much and eventually agreed to let her participate in the case. While Cheng Yao was at work, she took care of all the necessary arrangements for Qian Heng. Soon, a client arrived, and it turned out to be a popular celebrity. Cheng Yao was completely surprised by the client's identity and because they had signed a confidentiality agreement, all conversations that day would remain private.

The celebrity, Bai Xingmeng, and her husband got married abroad, but their marriage was not recognized domestically. They needed to go through legal procedures for their relationship to be acknowledged in their home country, which posed a difficult situation. Cheng Yao spent time and effort on their case, but in the end, nothing belonged to her. When Bai Xingmeng left, Cheng Yao was the one to see her off.

Cheng Yao sometimes felt that Qian Heng was too rational, and that emotions should take precedence in certain matters. Qian Heng showed Cheng Yao the time on his phone, and she immediately fell silent. In order to repay her debts as soon as possible, Cheng Yao arranged a candlelit dinner for Qian Heng. When Qian Heng returned, Cheng Yao warmly welcomed him, but he didn't even exchange a few words with her and went straight to his room to work. Soon, Cheng Yao's voice singing while cooking reached Qian Heng's ears, making him increasingly drowsy. He realized that he was falling asleep because of Cheng Yao's singing, but he still had to finish the tasks at hand. He asked Cheng Yao to stop cooking and singing, and after half an hour, Qian Heng finished his work. He lay on the bed, listening to Cheng Yao's singing, and soon drifted off to sleep.

Qian Heng woke up again in the middle of the night because he was feeling uncomfortable due to not having eaten dinner. When he opened the refrigerator, he found that there were dishes inside, but each one had a price tag. Qian Heng was too hungry to resist and ended up eating the food, but to be fair, it did taste good. Qian Heng was about to go back to sleep when he suddenly saw Cheng Yao sleeping on the table. He woke her up and gave her some time to ask him any questions she wanted. Cheng Yao was very happy and even took out her notebook to record everything.

Qian Heng also told Cheng Yao that a qualified lawyer should not only have knowledge of the law but also a little understanding of various industries. He gave her a direction for investigation, and the next task was up to Cheng Yao herself. Wu Jun saw a small dog at Cheng Xi's house and really liked it. He wanted to ask what happened between them that night, but just at that moment, Qian Heng called him and asked him to come back immediately. At first, Wu Jun wanted to refuse, but because Qian Heng called him in a professional capacity, he had no choice but to leave.

Wu Jun originally thought there was something important that called him back, but it turned out that Qian Heng's good news was simply that he had slept well throughout the night. Qian Heng explained all the pros and cons to Bai Xingmeng. If she waited another month before filing for divorce, she could secure more assets than she currently had.

Bai Xingmeng also mentioned the exciting circumstances of how she met her husband years ago. At that time, her husband's career had not yet taken off, and their relationship was very passionate. To protect her husband's privacy, she chose to have a secret marriage, but their secret was eventually discovered by the company, resulting in a huge breach of contract settlement. Later, Bai Xingmeng learned that her husband was the one who leaked all those rumors, which caused her career to plummet.

Cheng Yao was prepared to work overtime in the evening, but Qian Heng, in a professional manner, asked her to go home and rest. Qian Heng explicitly told Cheng Yao that she should not sing while cooking dinner, but she must sing while preparing late-night snacks. Cheng Yao found this very strange.
