My goodness, IU, and co-star Jin-goo did such an incredible job! The production felt so clean and exquisite, and each of Jang Man-wol's outfits was astonishingly beautiful. I was hooked from the very beginning, and the drama perfectly balances romance, fantasy, comedy, and soul. Many of the side characters had touching backstories, and I'm so happy the writers gave them each a satisfying ending! The OST soundtrack was one of the most memorable things from the drama, HEIZE and Chungha (to name a few) did a fantastic job adding a haunting and emotional touch to the deeper scenes. Easily one of the best dramas I've seen by far!
