A Delicate Wife is Promiscuous

A hardworking delivery man toils day and night, only to return home and serve his mother-in-law. His wife treats him coldly, and the mother-in-law humiliates him by demanding his wife entertain another man. When he protests, she mocks him: "Give me 20 million, then!" His wife, fed up, divorces him. Just as he hits rock bottom, a phone call reveals his true identity—he's the heir of a wealthy family, and his wrongful disgrace has been cleared.
