The president of a large company, Masahiko, sought some advice from a contractor, Mukai. Financial support to avoid bankruptcy … Mukai proposed to Masahiko, who was reluctant to nod, to marry his daughter, Ai, to Masahiko's only son, Naoto. Masahiko, who has been interested in AI for a long time, agreed and made a specific plan. Until the ceremony, Masahiko forbids premarital sex and denies Ae's sexual desires. And Masahiko, who is alone with the AI after paying Naoto and his wife for 5 days, completes the training program he dreamed of for many years.
