I don't know why this drama loss rating too early. May be because of it's weird type story in middle. But seriously 1st 5-6 episode was too good. And finishing was also not so bad. But in the middle this drama turn to be little bit boring. But i don't think this drama was too boring to lose rating like that. For romantic drama lover i think it was perfect. But one thing i always hate is too much or hardcore type love Triangle. And in this drama lead actress turns out to be a 2nd lead actor sister, it was too embarrassing, because they was in love Triangle and in one scene they also tried to kiss each other. I don't know why korean director can't think a single story without love Triangle, is it too much in Korea!!?? But in my Opinion for chemistry Between lead character this drama was more than enough, though it would be more better without love triangle( who turned out to be a brother). And story was sometime simple but they did so many illogical scene in this drama, so it turn out to be little bit boring. But not too much boring to ignore it.
