In order to break through the bottleneck of targeted drug research and development, Sheng Shaoyou goes to his friend's private club, hoping to connect with the mysterious X Holdings, but unexpectedly meets and rescues Hua Yong. Knowing that Hua Yong is trying to cover his sister's medical expenses, Sheng Shaoyou secretly pays for them and the relationship between the two develops.

Hua Yong confesses that he could only have an intimate relationship with the Alpha who 'permanently marked' him, which Sheng Shaoyou finds unacceptable. On the other hand, Gao Tu faces the pain of hiding his identity and pheromone imbalance, which Shen Wenlang discovers. Meanwhile, X Holdings makes a push that brings the business developments to a climax.
