The premise of identical twins separated is not new to KDramaland; however, this story is quite different as it was a twist of fate that separated them and the lives they lead was totally different. The acting by Uhm Tae Woong was excellent. It was believable as it acted as both twins that were so different; night and day. The revenge was sadden at the fact that the brothers had so little time together. The love story was not as important because the main characters were in love from the very beginning. I really enjoyed this. It had its slow moments but I enjoyed watching each of the players responsible for the deaths to get their comeuppance. Is it worth watching? Only if this type of genre is your cup of tea. As I love suspense, crime stories; I recommend this highly.
