First of all I didn't see this drama draggy as many said
It was nice, logical and funny
With cute romance and strong plot
But sure it has it's flaws

The end was annoying for they must be separated for no reason in my opinion
Because the grandmother promised if the gumiho finds herself a husband she will turn her to human and leave her at earth

The character of min woo was extremely Annoying and selfish
I saw him an enemy friend , a snake in a smooth way
He didn't help her actually he was just trying hard to take her away from seung gi to himself

What bothered me as hell that B**** soo Jin she didn't have any punishment for what she did

The main sad song was amazing I like it a lot
What surprised me so much was one of the main background track music was stolen from Egyptian song was released at 2004

Really recommend drama , I loved it
