Anata gonomi no (1969)

A man with a distaste for women convinces his businessman father, who owns a supermarket, to invest in a new venture, namely a school for brides and housewives. Thinking this may actually finally get his son involved with and married to a woman, the father agrees so long as the son becomes the principal of the school. Having acquired a school that was almost broke, the businessman finds the school's administrator may be useful for spying on his son. She accepts, but in exchange for a sum of money of course. In the meantime, the son institutes a contest for the pupils.
