Hiding the fact that he is an Omega, Gao Tu takes several days off work and avoids meeting anyone, which leads Shen Wenlang to mistakenly believe that he had another lover. Meanwhile, Sheng Shaoyou and Hua Yong finally enjoy a moment of sweetness after overcoming numerous obstacles, but an earthquake occurs. Hua Yong, in order to protect Sheng Shaoyou, unleashes an astonishing amount of power, causing Sheng Shaoyou to doubt whether he is really an Omega.

Sheng Shao You was kidnapped and injected with a deadly toxin. To save him, Hua Yong had no choice but to mark him permanently as Enigma. After the marking, the two become passionate and Shao You makes a confession. Meanwhile, Gao Tu makes a decision to resign, triggering misunderstanding and anger from Shen Wen Lang.
