If you're looking for a supernatural-light-horror-comedy-romance, then look no further. Master's Sun does a great job to live to that premise. When I read the story synopsis, I was like "hmmm, that can either go really good or really bad" and thankfully, it went really good. There are some great stories to explore, most ghosts' stories are well thought-out and executed (the effects and make up is a big plus + too) and there is also the kidnapping story that keeps the suspense on going. The characters aren't one dimensional, and they evolve on their own right too, as does their relationship; a big factor to help on that is that the main couple has great chemistry (GHJ seems to be having that trait with any of her co-stars). The secondary couples were also very entertaining to watch. (Kang Woo&Little Sun were the best!) The OST was very good- the main romantic theme stands out obviously but there are some nice light hearted songs in there too. The music score is nice, too. My only complaints are, that I felt like the last few episodes dragged out a bit more than they should, there wasn't a real resolve with one of the ghosts' storylines that kinda bugged me a bit, there were some conversations about a "dilemma" that went back and forth and back and forth and yeah, it felt a bit eeeer at some moments. Other than this though, it was a good series and I enjoyed watching it very much; Definitely worth my time!
