Number 1 favourite asian drama

i loved it from the beggining till the end, everything about it is perfect
the set, costumes and surroundings respects life in both north korea and south
the actors all play very very well
the chemistry between the 2 main actors is there and it can be felt
the plot is logic and has continuity
the story , ah the story, it's something you have'nt seen displayed like this
it has a happy ending, yay! i love the fact that the main characters gets in the end their happy ending despite everything they ve been through
