What an amazing journey! I was addicted to this drama from episode 1 and continued to stay addicted to it until the very last episode! It's a masterpiece to me <3 The story starts off so amazingly crazy and stays crazy good all the way until the end (at least to me it did). A lot of people seemed to have compared this to 'Secret' b/c of the writer - but don't. I honestly like the end of this drama much more than the end of secret. (I honestly was disappointed by something that happened at the end of Secret - but this drama left me with no disappointments. Story: [I wanted to edit this right away but MDL was shut down so it's updated a little late...] Byun Ji Sook is a hard working young woman burdened with debt. Seo Eun Ha is a rich heiress. They are doppelgangers (they look exactly alike) - when circumstances and situations shift, Ji Sook finds herself having to live the life of Seo Eun Ha. As she is pressured into this life that she didn't ask for, she at first does her best to survive & protect her loved ones (old and new), we see her character grow from a weak scared individual to a strong and brave woman who is willing to take a risk in order to set things straight. Enemies along the way try and hold her back and stop her as much as possible. Min Woo is the heir to a huge conglomerate and he wants that title but little does he know that someone has been messing around with his sanity. This drama is full of mystery, crime, romance, deception and uncovering truths. It's a melo in every way - but not your typical melo - It's breathtaking (maybe even more so if you marathon it - I personally watched 13 episodes in the span of 2 days! and watched week by week there-after) - but I knew from episode one that this would be a drama that would be best reserved for a marathon and I never lost that conviction. Cast: The entire cast did an excellent job! Joo Ji Hoon as Choi Min Woo portrayed a tormented man scarred with loneliness, pain, and lack of affection/love. His character is the most beautiful to watch. While he fights himself - fights to keep his sanity and fights to keep his belief in himself. He does his best to stay strong but in the process he avoids as much contact with people as possible - that is until Ji Sook enters his life. ^^ Soo Ae as Byun Ji Sook/Seo Eun Ha - she does a wonderful job showing fear, anxiety, love, hurt, pain and joy. Even if she wears a 'Mask' she still stays true to herself and is loyal and protective to those around her. Yeon Jung Hoon as Min Suk Hoon, he can pull of a bad guy so well - his face literally looked evil - with one glance of the eye, one lip twitch... he can be so creepy - he almost seemed immoveable. Yoo In Young as Choi Mi Yeon - I really pitied her character, I understood where she was coming from and where she didn't want to go - but she did a few things that no matter how much I understood her - it was still wrong... I would describe her as being stuck between a rock and a hard place - she was trapped in a cage she created for herself, and that was just sad. I didn't hate her - but I did get angry at her a couple of times. Soo Ae and Ho Ya actually look like real siblings! lol Music: The OST was simply BEAUTIFUL! I love each and every song! 'One Person' by Moon Myung Jin, 'It Hurts' by Zico & Sojin, 'I'll Pretend I'm Dead' by Chancellor & Vasco, 'One Day' by LYn, 'I Hoped It Was a Lie' by Navi, 'No Love' by Byul Ha, 'Where' by Yoon Do Hyun, 'Similar' by Junggigo, 'I Miss You' by Seo Eun Kwang & Mi Yoo - My personal favorites (I love them all though) are: One Person, No Love, Where and I Miss You ^-^ Re-watch Value: 10/10 - I will definitely re-watch this drama! To me it's a masterpiece, it may not have been perfectly perfect but I loved it! I highly recommend this drama and hope you'd enjoy it as much as I did :D
