I am only on the 6th episode and I really want to like this drama. When I am watching, I usually connect with a character and love to watch their story unfold. However, so far, I have been unable to connect to any character. All of their personalities are terrible. One is supposed to be super kind and gentle but ends up just looking weak and submissive, one is supposed to be the "hero" but just seems stodgy, and judgemental, one is supposed to be the anti-hero but just looks devious and cold, and the last one is the reason I want to turn off the entire thing. The sister that is supposed to be wild and mischievous is just bitterness in the flesh. All of her actions have a very bitter tone to them. Her rebellious nature just comes off as ignorant. She is thoughtless and mean, not in the least bit funny.
The plot really caught my interest because I am a big fan of that theme, but it has been a real disappointment and hasn't shown any signs of getting better. However, I will continue to the end and see if I can find the reason so many people gave it a great review. It deserves a chance and I will return with a final verdict.
