Bride of the Century (백년의 신부)
Starring Lee Hong Ki and Yang Jin Sung
In this fairytale-like melodrama, Choi Kang Joo (Lee Hong Ki) is the cold heir of one of Korea's most powerful conglomerates, Taeyang Corporation. He is engaged to an eligible young lady from a small southern island, Doo Rim (Yang Jin Sung), but there's just one problem: the first bride of the family's first son is always cursed to die. The curse began 100 years ago when the bride of the family's first son had a tragic death. Suddenly, before the wedding, Doo Rim disappears and the company conspires to replace her with a look-alike, Yi Hyun (also played by Yang Jin Sung), who has a sinister scheme of her own.
