Jan is a boy growing up in 1930s Siam in a wealthy, dysfunctional family where sex has a huge impact on everyone's lives. Since his mother died giving birth to him, the younger sister of Jan's mother, Aunt Waad, is brought in to care for Jan. Luang has sexual relations with her, which causes young Jan to be jealous, since he has developed feelings for Waad. From the beginning, he spoils her and teaches her to hate the "bastard Jan". Waad, in return, treats Jan like her own son and despises the spoiled and bratty Kaew.

Later, another of Khun Luang's women, the sophisticated nymphomaniac Boonlueang, moves into a guesthouse on the estate, and she teaches Jan his first lessons in the ways of love.
