I enjoyed the show very much. But after episode 15, I felt like the story was dragged out to try to redeem some characters. My original review had a lot of spoilers, so I deleted it. But the story is worth watching. I did feel like some of the characters were just horrible people and deserved bad endings. Even when some of those characters started to change, after so many episodes I didn't feel anything for them because I thought that they were horrible. But this drama is good, I could see myself rewatching it again.
