Since it's a short drama I'll give it 10/10 for everything. I think it's difficult to judge it comparing to standard length drama. So for a time limited length short drama it's really great.

It has a feel of goblin. Definitely understand what I mean from just episode 1. Also has reference to goblin too. I like that drama and I like this one too. This one is a really short drama where as goblin is full length. I think if you liked goblin which I think everyone who seen it does then you'll like this one too. The ending however just felt like end of a episode not really ending of drama. So it was a little strange how it ended just like that. Didn't even feel like it was the last episode last scene at all. If you do watch it you know what I mean. Korean drama don't usually do season 2 so I don't think there will ever be more. But overall great especially it's a short drama so no reason not to watch.
