"My Obsession" is a light-hearted and humorous family drama that tells of the farces and love stories between three families with distinctive characteristics. In the drama, the three distinctive families are closely related to each other. Except for dealing with their own trivial family matters, these family members also have to face up to the entangled conflicts among the three families. The three families make noise and have quarrels every day, in which there are subtle factors of love. At last, the three originally unrelated families become one family. One family is arrogant and prejudiced. One family is a model of kindness, courtesy and harmony. Another family is selfish and does not care about others. Such a family that seems impossible to blend like water and oil becomes one family as they come to like each other after arguments and misunderstanding.
