Masahiko, the president of a large company, received a certain consultation from a subcontractor, Mukai. Financial assistance to prevent bankruptcy... Mukai proposed to Masahiko, who was reluctant to shake his head, to marry his daughter, Ai, to Masahiko's only son, Naoto. Masahiko, who has been interested in Ai for a long time, agrees and plans a plan. Until the ceremony, Masahiko forbids premarital sex and corners Ai's libido. And Masahiko, who paid off Naoto and his wife for five days as a business trip and was alone with Ai, carried out the training plan he had dreamed of for many years.
