disclaimer: thank God I dint know about the webtoon version.

The storyline - not bad at all. unraveling the curse and lifting it they kept the story intact. mountain God (gumiho) holding a grudge has definitely gave me a vibe of tale of nine tailed but it's not exactly copy.

the cast was good. the kisses were fire!
the supporting charecters got their own story which I liked.

what I don't like is it could be finished in 12 episodes. they dragged a bit. else it's alright.
if someone can buy the plot of kind the land (like the most common 3rd gen chaebol guy with childhood trauma) then I don't know why the same audience did dirty to this show.

ignore the reviews, go watch. I know you will feel it's dragged somewhere, so just fast forward those parts. but just watch. it's not as bad as the reviews are saying!
