Ji Su-Bin, a novelist of a prize novel 'I-A', makes a brilliant debut in the world of literature. But the novel is not hers but her sister's, Su-Hwa, who lives in a mystery after a false notice of death because her face is covered all over with wounds due to a fire. Su-Hwa described the limit of man and love with love to Sang-Hyeon. Su-Bin gains fame more and more, but Han Pil-Hun, a journalist who deduces Su-Bin's family and the world of her work, reveals the truth.
