Fairy

I think I liked the idea that Moon Soo became a ghost....but then they said how to solve it and were like "we'll just live with like that, who cares, we don't want to break up." It wasn't even a "we have to stay away for x amount of time until you get old/lose your powers an then we can reunite"....which even that would've been better. I'm just like after finishing the last episode "okay....wat, did it just end like that?"
