What an excellent drama! It's up there in my favourites list now with Healer and Faith. The story was great. It was great to see something totally different. It was well written and the pace was perfect, it was slow when it needed to be slow, and fast moving when it needed to be fast moving. It was quite a simple story but so beautifully told. It was hilarious and it made me cry (I'm not a cryer usually). The writers did such a great job without leaning on tired tropes The actors were expert. The only one I was familiar with was Kim Seul Gi, which was why I watched this drama. She's fabulous in everything she does even if the drama is not so great (I'm looking at you "Flower Boy Next Door") . The lead actress Park Bo Young was so wonderful to watch. She essentially played 3 personalities in this and was convincing in each of them. The lead actor Jo Jung Suk was great too. I'm not sure why but i really didn't want to like him, but he'd won me over by the second episode. All of the actors were superb. There wasn't a single character, minor or major, good or bad who I didn't care about by the third episode. It's nice to see a well played bad guy who is not a walking cliche - two thumbs up to the actor (i don't want to say who it was for fear of spoilers) for being just the right amount of creepy and the writers - great job!. Rewatch value is right up there. I would watch this again...and again. It really is a classic drama. RECOMMENDED!
