Episode 16 recap: Chu Xin confirms that Chu Ze'an is indeed Chu Zejia.

After realizing that Chu Ze'an is Chu Zejia, Chu Xin used her strengths to deduce their zodiac signs and discovered that this month is a month of rapid progress in the relationship between Chu Zejia and Yan Zhen. She couldn't help but feel excited. Yan Zhen and Chu Ze'an were lying comfortably on a long bench, basking in the sun. Yan Zhen asked Chu Ze'an with hidden intentions whether he felt guilty towards his loved one after being apart for four years. Chu Ze'an tactfully explained that he has been alone for the past four years and used the excuse of finding a book to quickly leave.

Suddenly, Gu Cheng called Yan Zhen and asked if she was going on vacation. Chu Ze'an also joined the trip. After receiving confirmation, he reminded Yan Zhen that the paparazzi had already taken photos of the rumored relationship between them as brother-in-law and sister-in-law. He advised them to return quickly. Yan Zhen and Chu Ze'an decided to let the public relations department handle the matter, and they both felt that someone behind the scenes knew about their investigation into Lu Nan and used this scheme.

After seeing the news, Chu Xin wanted to confirm her suspicions, so she decided to stake out Chu Ze'an at the hotel. At that moment, Chu Ze'an was exchanging information with his contact. When he noticed Chu Xin's poor acting, he made his contact leave first and quickly slipped away while Chu Xin wasn't paying attention. When Chu Xin turned her head, she couldn't see Chu Ze'an and became anxious. Yan Zhen appeared and directly exposed Chu Xin's identity. Chu Xin had realized that she had misunderstood Yan Zhen all along and apologetically acted spoiled while apologizing to Yan Zhen. She was thrilled to learn that she could sleep with Yan Zhen tonight and immediately hugged her.

While enjoying sweets, Chu Xin deliberately used a ruby necklace as bait to confirm that Chu Ze'an is Chu Zejia.
