The casting choice for the sisters couldn't be any more perfect than this. I've always thought Ha Ji Won and Kim Ha Neul looked strikingly similar, you can even add Nam Sang Mi to the mix. The drama itself was a mixed bag. They did a poor job in establishing the sisters' relationship and even a worse job in shaping Ji Eun and her motives to play the antagonist. The problem further continued with the character Jun Ho and his initial relationship with the sisters. There were clearly glaring issues with writing the characters in this drama. The story was revolving around the secret but when it came time to address the secret it was a bit too late to do anything substantial with it.
