Feng Shui master Che Zhen (played by Chapman To) has been lustful since childhood and is now addicted to sex. He and his good friends, director Wong Jingwei (played by Zou Kaiguang) and doctor Chen Shisan (played by Pang Ho-cheung), are like-minded and tirelessly accompany each other in the entertainment field. Che Zhen made a mistake in his busy schedule and had a date with two women at the same hotel at the same time. He had to go upstairs and downstairs to cover it up. Although he was eventually discovered, he met Zhou Zhiling (played by Chrissie Chau), a female veterinarian who was also multi-romantic. Soon, due to an accident during Che Zhen's sex life, the two met again. Zhou Zhiling felt that she had feelings for Che Zhen, but she was not sure whether she could get along with Che Zhen, who was also a slut. At the suggestion of her sisters, Zhou Zhiling proposed to Che Zhen, but the condition was that the other party would not have sex and could not cheat within three months. Che Zhen gladly accepted the challenge. However, in addition to dealing with the repeated seductions of Zhou Zhiling's sisters, he also has to face the appearance of his former goddess He Jiaxin (played by Tong Fei) and the pursuit of Zhou Zhiling by the rich boy Li Zhaokai (played by Liu Haolong)...
