One Percent of Anything starring Kang Dong Won and Kim Jung Hwa
Kang Dong Won brings his usual charm and boyish good looks, and drama veteran Kim Jung Hwa (Snow White, When It's at Night) is a perfect casting match.
When kind-hearted school teacher Kim Da Hyun helps out an elderly man on the subway coming home one day, she unknowingly sets into motion a matchmaking whirlwind with his wealthy, but cold grandson, Jae In. Inspired by her kindness, the old man, Chairman Lee writes her into his will as his inheritor, with the stipulation that neither of his grandsons will get a cent of the inheritance unless they pursue and marry her. Jae In, who has displeased his grandfather in the past, is furious at this unexpected turn of events, and questions Da Hyun's motives.
Nevertheless, he decides to pursue her to ensure that the other grandson doesn't gain an advantage. Unfortunately for him, however, Da Hyun repels his tainted advances. The spoiled rich boy soon finds himself oddly drawn to the strong-willed and independent woman. In between arguments, the two begin to fall in love, but they'll have to face many more obstacles on the path to happiness.
