Episode 15 recap: Chu Xin suspected the identity of Chu Zean.

Gu Cheng worried that there might be someone else behind the Ma Jun, so even if Ma Jun left, Yan Zhen wouldn't be safe. He decided to meet with Chu Zean and asked him about the reason for his return. Chu Zean took the opportunity to openly ask about the person behind the explosion case involving Chu Zejia. Unexpectedly, Chu Zean found out that Gu Cheng also didn't know who the mastermind was. Yan Zhen knew that Lu Nan was not dead, but she didn't know where she was hiding. Thinking about Chu Zejia's forced acting, a smile appeared on her lips. It turned out that Chu Zean's acting skills were full of flaws in her eyes.

Yan Zhen deliberately packed up Chu Zejia's things to throw them away. When she saw Chu Zean returning, she asked him to do it instead. Chu Zean looked at the limited-edition figurines and the photo of him and Yan Zhen, feeling heartbroken. He understood that Yan Zhen wanted to start a new life, and he didn't object to it, but there was no need to throw away these things. Yan Zhen revealed that she already had someone new in her life, so she needed to make room for the new person, and that person was Chu Zean. Chu Zejia couldn't believe it. He had actually been cuckolded by his own brother.

Yan Zhen knew that Lu Nan had a sister who worked as a customer service representative and decided to take a risky move to find her. Chu Zean thought it was too risky, but Yan Zhen insisted because she believed there would be a surprise. So, the two of them checked into a hotel under the pretext of being a married couple, using the excuse of losing jewelry, and requested the hotel to provide the shift schedule of the room service staff for them to personally interrogate.

While Chu Xin was doing a live stream about calculating horoscopes, she remembered that many people's birthdays were not the same as their ID card birthdays. Chu Zean happened to know Gu Cheng's real birthday, which made her suspicious.
