This was a great drama. I really only watched it because of Jung Il Woo and he stayed my favorite character all through it (which usually doesn't happen), but I liked the rest of it just as much - Otherwise I wouldn't have watched 20 hours of it. In two days. The story itself wasn't new and most of the characters were a little stereotypical, too, but somehow it was still different. I liked how people were somehow related to eachother through tiny memories they couldn't even remember, things nobody thinks about after so many years. I loved how the world was turned upside down for a character and the story followed a clear path, a clear timeline and had a steady pace. It hardly ever dragged, but it never rushed either. The acting was incredible. All the actors did a great job, but of course Lee Yo Won needs to be mentioned seperately - She played 3 roles in this with about 335345 personalities and so many emotional and blank scenes that I was completely amazed by her. She seemed completely in character, no matter which one she played. The music was wonderful, too. I actually noticed it and really enjoyed it. From Ji Hyun's singing to her parents' CD to the Scheduler's ringtones - Everything just fit perfectly. Though many people seemed to hate it I thought the ending was perfect and the only fitting one. Everything else would've been unrealistic (I know. This is fantasy.) and maybe perfect at the first sight, but I wouldn't have been satisfied afterwards. I loved it as it was, except one little storyline. But that wasn't important and I cried a lot. Enough praising, just watch it. :P (This must be my longest review ever..)
