it was interesting at the beginning but it became to lame and obvious when it proceeded. it's not bad. worth to watch one time.
They could have added more magical elements to the story but emphasized on their love which was really boring to watch. I mostly skipped their romance part.
The side characters are pretty good and kept the show for me. and the second leads where too.

And I don't know if a breakup scene is really an unavoidable scene in almost every KDrama. it's like the writter just wanted to include that scene so they made a lame excuse to break them off.... ughh ..
But still it was pretty good watch.
And I will never watch it again. ?
