Synopsis
Kim Da-hyun is a kind-hearted elementary school teacher who helps an elderly man who passed out behind her school while she was in the middle of her class. The "old man" turns out to be Chairman Lee, a multimillionaire CEO of one of the largest conglomerate corporations in South Korea, and Da-hyun's act of kindness towards the Chairman leads to a series of strange events. She is written into his will and stands to inherit all of his fortunes. The Chairman's two grandchildren will see none of the inheritance, unless they choose to sincerely woo, win, and marry Da-hyun. Caught in this web is Lee Jae-in, one of Chairman Lee's grandsons, who had worked hard to rise in the corporate world without his grandfather's help. At first unwilling to play his grandfather's game for control, Jae-in is abrasive and constantly fights with Da-hyun as they attempt to negotiate the strange turn of events for the better. In the end, the two fall in love despite the differences in their personalities, objections from their families, and other obstacles.
