I watch a lot of KDrama and have for about 6 years. No, this is not "the best KDrama ever" because there are too many excellent series, and there is no such thing as the "best" one for all viewers. This drama is a sweet, charming story-a fantasy that also asks serious questions about what makes a human...human. The lead actors are talented and delightful in their characters; supporting cast is also good, except the villain is so far over the top he becomes a cartoon character for me, and I became bored with him, really ticked when he was too much with us in the finale. Still, despite my wanting to slug the boring bad guy, I did love this series, especially the lead actors, and highly recommend it.
