An intense drama with a heavy plot this one. The story has so many leyers that sometimes it wasn't easy to keep up. However, the many twists and the drama from the past were really entertaining. This drama follows the japanese original closely, but add it own touch to it, with the final ending similar and yet very different. Actually, the ending was a shock and it suited the relationship overall, the later being a very well presented one, as the two actors had chemistry. There were two things however that I didn't like about this drama : they left some things unconcluded and unexplained (a); Jin Kang was sometimes annoying as a character (b). But, overall, it was a great drama, so 8 out of 10.
