My Fake Farmer Husband Is a CEO

On a bus, a young man speaks rudely to a scavenger-like old man, complaining he's dirty from work. A woman steps up to defend him. After getting acquainted, she begs the old man to pretend to be her husband to deal with some trivial matters, unaware that this gentle old man is actually the chairman of a corporation. Over time, their fake act blossoms into real affection, and the two elderly people eventually join hands in a warm, late-in-life marriage.
