Same theme movie i have watched many times , time span like that ,resembled stories enter into the game so basically the theme was same .
Starting episodes were good then middle of the episodes were little borring and then ending was good .
The differrent in the story was it had shown that one city was woman dominant and other city was man dominant city . so how these dominant power entangled with each other and how end went and how they came back to present life .so this was in the story .
I think the drama should have one more episodes of their present life where they first realised that was not a dream actually that was real and he search her not she . something like this should be there or may be the drama should have both the part historical one and the real one with 15 and 10 episodes respectively so something good may be come out.
