Episode 18 recap: Huowen is seeking the design rights for the South Carat Diamond.

Ji Yunxiao tried to take credit for himself by telling his father that he had been in communication with Huowen recently and had finally reached an agreement with him. He claimed that if he were given the design rights for the South Carat Diamond, it would be an excellent addition. Ji Rong praised Ji Yunxiao for his efforts but suggested discussing the design rights with Ji Lingsu because Huowen was a newcomer, and it was concerning to entrust such an important responsibility to him.

Ji Yunxiao informed Tang Ruoyun about this outcome. At that moment, she started to have malicious thoughts. Lin Yumeng secretly read news about Ji Lingsu, and Zheng Ying noticed that she had developed feelings for him. Zheng Ying even mentioned that Ji Lingsu's concern for her seemed genuine and that their relationship was more than just a fake marriage. Right after saying this, Ji Lingsu called and asked if she had applied medication and mentioned that he would return to the country tonight.

Zheng Ying advised Lin Yumeng to find out Ji Lingsu's feelings for her in their daily interactions and to withdraw if he didn't reciprocate her feelings. That night, Lin Yumeng took the opportunity to inquire about Ji Lingsu's feelings, coincidentally catching him while he was changing clothes. Ji Lingsu embraced her directly, expressing how much he missed her, and couldn't help but kiss her. He also worriedly looked at the scar on her back. The scab was already itchy, and Ji Lingsu's gentle application of medication made it even itchier. Their voices attracted complaints from their neighbor, Wanting, who knew that they lived next door but had no idea about their lack of self-restraint.

Wanting suspected that Lin Yumeng and Ji Lingsu's relationship was not just a fake marriage. Meanwhile, Ji Lingsu bought a gift for her from abroad, and when Lin Yumeng went downstairs, Wanting quietly entered their room.
