I have to say I enjoyed this special more than the drama. While the drama got repetitive with the going back in time, this had just the right ammount. The plot of this was excellent and I liked how the premise was helping to prevent what happened at the original wedding of Tsuru and Eri. I loved how this tied up some of the loose ends of the drama and the ending scene itself was really cute between Ken and Rei. Ken's character changed a lot for the better. All the other characters as well matured and changed for the better too. I thought the acting in this was a huge improvement to the drama. Ost for this was great as well and I would definately rewatch this over the whole drama itself as this has a good story.
