Wow, so stunning. Though I will confess that my mind is turning circles on the time travel thing. Which I will address first so I can get on with my gushing. So future Soo Hae's body was not occupied by the REAL Soo Hae of the past. Instead she almost drowned, passed out, and then was in a comma for a year. While in the past as Soo Hae she lived a read morepretty long time and did a lot. (Time jumps! Tons of time jumps!!!!) Why didn't the past Soo Hae occupy the future girl? Did she just die and Soo Hae took over all reincarnations? Hmmmmmmm.
Okay, I am a sucker for tragic romances. Though sometimes I'm more angry with them. After all it's the stubbornness and stupidity of the lovers that usually lead to their predicament. In this case you understand both and realize that they're longing for each other and trying to move on is part of that problem. It broke my heart and the grief they had for each other at the loss was moving.
My poor Jung (aka the 14th Prince). It baffles me that Soo didn't KNOW. Then when the 13th Prince comforted him, oh my heart.
Truly everything pulled together well. I'm sure some fans are not satisfied with the ending. However, I love that So believes that he will meet Soo in another life. That he will find her and that they will be together. The ending scene may have not been them meeting up in the future, but it left their tragic romance in one of their happy moments. Love isn't always the good times. With what we see of Soo in the future I believe that they will meet.
While I'm satisfied with this ending I will admit I'd have loved to see them in the future together. More importantly would future So have a scare? ^_-
