PLOT : The storyline is based on a Korean folk tale about you guessed it  Fairy and the Woodcutter. But the kick is, you don't know until the last episode who really is the woodcutter and what happened in the Fairy realm.  It's such a cute story and the actors really portrayed it well. The Plot was very well built, I loved the other fairies(they gave us some of the best scenes in the whole drama). My favorite person in this Kdrama was Jeom Soon, the daughter of Fairy and the Woodcutter, who can change into a tiger and writes one of the most popular fanfics on the internet.
THE CHEMISTRY BETWEEN OUR MAIN COUPLE(S)? : So from the first episode, we are told that the woodcutter is the rude and cold  Professor Jung Yi-Hyun, at least that's what our Fairy thinks. But the sweet and nice student Kim Geum starts to think he could be the woodcutter too. The chemistry was good between both of those couples, I seriously was guessing until the last episode who was the woodcutter and I can say that I was wrong in my guesses.
HOW IT ENDS: Unexpected! That's the only thing I can say without spoiling the ending! It's such a great KDrama and I definitely recommend you to check it out!
