It lacked character development. Also I hated the fact that the whole "Who's your daddy?" was dragged for too long. I only finished watching because I hate starting a drama and leaving the story incomplete. The first ten episodes were fine, but after that it just felt forced. I found myself watching but not enjoying the story. It just felt dragged for too long with twist that were not surprising to me. If there is anything that saves this drama for me is Tae Hee and her way of stuffing her face with cake.
