This drama is in a genre that I haven't watched much of, I tend to watch rom coms but I now have an interest in watching Melo/suspense/romance dramas.

The story is well set up, the initial episodes are gripping and made me want to keep watching, the story is very dramatic, it has most of the elements of a melodrama, doppelgänger's, birth secrets, switched identities, revenge, murder, blackmail, corporate greed, secret affairs the works. For the most part the story handled these themes well, my only problem is that some of the plot lines that were established earlier in the story were not resolved at the end, the most annoying one being "were Seo Un Ha and Byun Ji Sook biological sisters?"
The love story between Un Ha and Min Woo is very charming and sweet although I wasn't crazy about the lacklustre chemistry between the leads;

Soo Ae's portrayal of Eun Ha and Ji Sook was spot on, she managed to give each character its individual identity so that the two were very distinct. Her steely determination and quiet strength were very well executed.

I found Joo Ji Hoon's acting to be quite wooden, he doesn't seem to have many facial expressions; he had an excellent script and role to work with though and I think that was his saving grace. I will admit to him being charming though.

Yeon Jung Hoon's portrayal of Min Seok Hoon was great, he gave the character sufficient menace without being inelegant, He was cooly focused on his revenge mission and used every weapon and opportunity at his disposal to achieve his goal. I will say though that the story set him up for big things which I feel he ultimately didn't live up to.

The character I enjoyed the most in the drama is that of Choi Mi Yeon played by Yoo In Yung. For the majority of the drama I found her irritating so I shouldn't say I enjoyed this character, it's more accurate to say that when I finished the drama hers was the most complex, subtle, and many layered character in the show. Mi Yeon is not simply good or bad, she has so many layers in between and varying shades of grey that she was often frustrating to watch. Mi Yeon's inward struggle was always on show, her constant battle to do the right thing while trying to hold onto a husband she clearly knew cared nothing for her was heartbreaking to watch, her moral compass was so shaky that half the time she didn't want to know what was truth or lies, preferring to make up her own reality. Ultimately she realises that she cannot live a lie or bury her head in the sad any longer. this is a sterling performance from Yoo In Yung.

The music is good background, and suitable for the action on screen.

I don't usually rewatch shows that have a suspense premise, because I already know what's going to happen.

Overall I give this show a 7.5
