The series mainly revolves around the lives of three couples and the difference between men and women.
Steven and Wenjing have been married for 8 years and have 2 children, Wen Wen and Fang Fang. Wenjing is a naggy and fierce housewife who is constantly arguing with Steven over issues such as Steven's gambling habit. Steven's mother, Ya Yu, moves in later and sows discord between Steven and Wenjing, as she hopes to find a better soulmate for her son by bringing Steven's ex-girlfriend, Ai Mei, back into the picture.
William and Ziling are a pair of newlyweds. Their relationship runs into problems when Ziling finds it boring to be a stay-at-home housewife and when Carmen seduces William. The strain in the relationship is further worsened when William finds out that he has a low sperm count and he feels he can't fulfill Ziling's wishes of having a baby.
Carmen and Hanns have each experienced a failed marriage before and have thus lost trust in the opposite sex. The two started out hating each other but eventually learn to give love another try.
