I wanted to watch this for Ahn Jae Wook, but unfortunately his role was so bad I ended up skipping most of his scenes :'( and instead ended up watching & finishing it for the Twins story (Go Soo & Kim So Yeon). The central story is about how twins who were estranged from each other, find each other and become a family. I feel like this drama was drug on for too long - I think it would have been better if it ended with 30 episodes instead of 50 b/c honestly I lost half my interest and became bored by that episode mark. I was just rushing through the last 20 episodes :/ I liked Kyeong Bin the most (Go Soo) and really enjoyed seeing him do his best to become real twin siblings with Seung Ni/Yu Kyeong (Kim So Yeon). They fought a lot after they first met, but eventually started warming up to each other and caring for each other. I enjoyed their journey. Su Chul (Ahn Jae Wook) was a liar and a cheater and I hated his relationship character - I did think he was a good friend and brother - but a horrible lover. (and this is coming from a fan of him). I think this was his worst drama. I really liked Nam Kyeong (the second sister - curly hair - Kim Ji Young) she reminded me a lot of actress Lee Tae Ran (a favorite actress of mine), she was nice and supportive to her siblings, honestly she seemed the like the oldest - like the leader of the pack if you will ;P Chan Mi was a good friend and I liked her role. Hwang Soo Jung plays the mute sister and she did a great job with her sign language & expressing emotions - I liked her for the most part - but ended up skipping half her scenes b/c she is mostly with AJW... :/ Music was EXCELLENT, I loved it! I have it listed in the comments <3 I will not re-watch this drama and unfortunately I do not recommend it - not even to AJW fans like myself. Go Soo fan's might like his part in the show though - I know I did ^^
