Plot
Ruby and Runa are twins, although one, unbeknownst to both, was adopted, and are one the opposite of the other: Ruby is responsible, obedient and kind, while Runa is manipulative, selfish and greedy. When Ruby announces her engagement to Bae Kyung-min, the jealousy Runa harbors for her sister sharpens: it has always been her dream to marry a rich man, but instead she remained pregnant with her boyfriend Na In-soo. Soon after, the two sisters have a car accident which disfigures them. Since Ruby's engagement ring and clothes are found on Runa, doctors reconstruct their faces swapping them. Runa has now the opportunity to live as Ruby, who, when she wakes up from a coma and discovers what her sister is doing and that In-soo, while knowing the truth, is not going to do anything, plans revenge.
