Episode 4 recap: Xu Jia Yin discovered a pair of eyes that resembled Yan Qingqing's.

Su Pan had put in a lot of effort to acquire Yuanke, but unexpectedly, Xu Ke Ji emerged as a competitor and disrupted her plans. This left Su Pan feeling disappointed. Uncle He knew that Su Pan had tried her best but couldn't secure Yuanke, so he comforted her, assuring her that her efforts were not in vain and that she shouldn't worry too much. Dai Zhi Yong called Su Pan, hoping she could answer a few questions. Su Pan initially didn't want to go, but Dai Zhi Yong was determined, so she reluctantly agreed.

At the police station, as soon as Su Pan entered, Dai Zhi Yong dismissed the people in the office and showed her a video taken at Lu Shan's house, asking her to identify the person wearing a cap, who was suspected to be Xu Mai. Su Pan claimed not to recognize him, but Dai Zhi Yong pointed out that Xu Mai entered Lu Shan's house just ten minutes after Su Pan. He suspected a connection between the two, but Su Pan refused to admit anything. Dai Zhi Yong hinted that everything would be revealed eventually and then mentioned that Su Pan resembled her sister. Su Pan was offended by Dai Zhi Yong's remark and became somewhat angry, preparing to leave while mocking Dai Zhi Yong for making up stories. However, Dai Zhi Yong sincerely mentioned that he lost his sister when she was seven years old. Su Pan paused for a moment, turned back, but didn't say much, and Dai Zhi Yong didn't pursue the topic further.

Xu Ke Ji was brought to the police station for questioning, and he immediately recognized his son, Xu Mai, in the surveillance video. He assured Dai Zhi Yong that if Xu Mai had done something wrong, he would handle it accordingly. The current challenge for Dai Zhi Yong was that they couldn't locate Xu Mai. Xu Ke Ji was also unable to find him as Xu Mai had left his phone at home and disappeared without a trace. Xu Ke Ji had stationed someone outside Xu Mai's house and promised to notify Dai Zhi Yong if there were any updates.

Unable to win Su Pan's affection and aware that Su Pan loved Lu Jiang, Xu Mai felt down. He ended up drowning his sorrows in alcohol and accidentally drank too much. He went to Lu Jiang's house and, while discussing life philosophies, fell asleep on Lu Jiang's couch.

The next day, while out for a morning run, Lu Jiang encountered Xu Jia Yin. It was clear that Xu Jia Yin had intentionally created an opportunity to meet. Although she referred to Lu Jiang as a ladies' man, she was genuinely surprised to learn that Xu Mai was at Lu Jiang's house. However, Xu Jia Yin didn't want to waste the rare chance to run with Lu Jiang and decided to finish the run before taking Xu Mai away. This struck Lu Jiang as peculiar.

Xu Jia Yin went to wake up Xu Mai at Lu Jiang's house, but before she could take him away, Xu Ke Ji arrived with his men and took Xu Mai without saying a word. Lu Jiang, hearing the commotion, came out to investigate while shaving, and sparks almost flew when his gaze locked with Xu Ke Ji's.

Lu Jiang suddenly saw a photo of Su Pan and Xu Mai meeting privately and couldn't help but ponder. He got into his car and was about to go find Xiao Zhi when he unexpectedly saw Xu Jia Yin sprain her ankle. Taking the initiative, he offered to drive Xu Jia Yin home. Xu Jia Yin alternated between finding Lu Jiang's assistance advantageous and criticizing him for not showing concern when she got hurt and not offering a helping hand. This left Lu Jiang feeling helpless. In the end, he simply let Xu Jia Yin lean on him as they walked, and he escorted her to Xu's house.

Pan Yue Yang was already in the hospital, and when he saw malicious reports about Su Pan and Xu Mai, he couldn't help but feel furious. He quickly called Lu Jiang, asking him to find Su Pan. However, Su Pan couldn't be reached after the incident, and Lu Jiang had no idea where to find her.

Lu Jiang felt that he should take off his police uniform and go help. After all, Pan Yue Yang had patiently waited for him for so many years, and now it was the Pan family's difficult time. He shouldn't refuse to help. But as the clues of the case emerged, he couldn't let go of the investigation either. The technical investigation department discovered from the surveillance footage provided by Lu Jiang that someone had secretly entered Lu Shan's residence and placed drugs in a drawer, proving Lu Shan's innocence. Dai Zhi Yong immediately went to release him.

Lu Shan, who had been held at the police station for several days, was already disheveled. He was angry and questioned Dai Zhi Yong about who was scheming behind his back, which made Dai Zhi Yong somewhat embarrassed. When Lu Shan returned home, he saw news about Su Pan on his phone, which made it hard for him to stay calm. He immediately called Su Pan, but there was no answer. Lu Shan immediately took a taxi to Pan's house, but Su Pan wasn't there. Coincidentally, Pan Wang fell ill, and Lu Shan helped feed him medication. Learning that Su Pan had left early in the morning and that Lu Jiang had left a message on WeChat, warning him not to believe the information online, Lu Shan couldn't stay calm and went out to find someone.

Xu Jia Yin inadvertently overheard Lu Gao Yuan mentioning a few numbers on the phone. She immediately wrote down the numbers and followed this clue to find Gong Qi. There, she discovered that Gong Qi had a pair of eyes that resembled Yan Qingqing's.
