I don't know why so many ppl gave low ratings...upto epi 4 it looks like a normal kdrama but after that it is so much interesting..this drama deserves much more gud ratings..ofcourse there r some holes in plots but while i watch the drama u ll never hav d time to look into d flaws..ost is so gud and visuals are mindblowing..kim go eun is a really something..she shows variances in everything..i love this drama❣ lee min ho acted well and every characters had a backstory and that was heart warming too..this drama made my heart to flutter , broken at last 4 epi
