It was full of dramatic twists and turns, a well-acted and compelling set of characters, and it was just a bunch of fun. It's not a show where you turn your brain on to think about how "logical" things are; it's a drama, intended to have dramatic moments, regardless of how much sense they make. While some plot elements were repeated (plenty of hurt/comfort for those who are fans), they made them slightly different each time which made it not feel repetitive. I think the two main leads really made the show. Both actors did a great job, and I think they had good chemistry. Some of my favorite scenes were when Hong Hee-joo was speaking on the phone to Paik Sa-eon, as they had great banter during those scenes. I think the length of the show was appropriate, as it didn't drag on and overstay its welcome. Nor did it feel like they cut the show short or rushed the ending. Overall, it's a pretty solid show.
