This is a wonderful fantasy costume production with great actors and a storyline that keeps you engaged in the love story between a human and an immortal spirit. The story is heartwarming, funny, mysterious and a little heart wrenching.
So if you love a mostly lighthearted, good fantasy love story with some twists and turns, this is definitely well worth watching.

The summary should have rather been something like this:
FL is the future immortal spirit Queen but that causes her to be quite lonely. One day she wishes for a friend and meets ML, a human boy. In order to save him, she gives him her spirit Orb, breaking the rules of her race. So, 10 human years later, she goes to find the now grown man - only to find that he is now a fierce spirit hunter and that retrieving the Orb isn’t that simple. To have a chance to retrieve it, she has to join the organization of spirit hunters he is a part of, starting a wonderful love story.
