Ok, this is one of my favorite dramas of 2015. I read some of the reviews before writing this and I was like... really? This drama gave me a ton of feels and kept me looking forward to the next episode each week. Compared to the other airing drama that I was watching with this which is still stuck on ep 3 (sorry High Society), this one, I was supposed to watch with my friend but I could never wait for her so we ended up watching this separately. STORY Byun Ji Sook is a hard worker trying to help her family get out of debt. Seo Eun Ha is a rich girl who doesn't really have to work hard for anything. They look alike but their not related. Circumstances happen that end up with Byun Ji Sook taking over Seo Eun Ha's life. How long can you keep a secret? How long till living a lie eats you up inside. A story about greed, revenge, family politics. This story has everything, romance, mystery, drama, intrigue, slice of life. Whenever a drama takes me on an emotional roller coaster, it's a good one for me. ACTING/CAST Soo Ae was pretty good at portraying two characters who are polar opposites from each other. I've only seen her in one other show and it was the movie "Sunny" which I can't really say I liked her acting there. I can't remember her acting there. >_< Joo Ji Hoon, what can I say, I just love him. I love his stares and this acting reminds me of when he was Prince Lee Shin in "Goong". Yoo In Young was pretty good at playing the annoying older sister. She has the perfect villainess look. :D Yeon Jung Hoon, now this guy wore his mask real well. I don't know how he could keep lying with a straight face all throughout the drama. He is one of the characters I love to hate. I just wanted to shake him. Hoya, I saw him in "Reply 1997" and I like him in Infinite. But this drama, I really loved him more. He wasn't like in a lot of scenes but in the ones he were in, he's showing some promise with his acting. Jo Yoon Woo, I want him as my secretary :D. He really cares for his boss and he's just too darn cute. MUSIC: Lyn's song "Just One Day" I can just keep listening to it over and over. Navi's "Tell Me A Lie" is pretty good too. I really like the instrumental during the Ji Sook/Min Woo moments. RE-WATCH VALUE: Yes, I would re-watch this. I like watching the main characters' journey of overcoming the multiple obstacles to their happiness. How they did their best to protect the ones they love. OVERALL: I would recommend it. If you like a little mystery, intrigue, romance with great actors then this drama is a good one to watch.
