Three years ago, Choi Moo Gak lost his younger sister in the "Bar Code" murder case. Since then, he has become cold and insensible, as he lost his ability to taste, smell, and feel pain. Meanwhile, Oh Cho Rim miraculously survived that the same incident. Since then she has lost her memory, but also gained the ability to see smells.
