This 16-episode supernatural drama is decent and worth-watching. The suspense? It will keep you going. There is this certain character who'll make you curious, and some mysterious events which the writer skillfully plotted so that these questions won't be answered until you completed the entire drama. The romance? There is more than enough of it; therefore, those who love romance dramas will definitely fall for this one. As for me, I had a love-hate feeling since episode 7. I realized that I liked Shin Sun Ae so much—and bled for her, too—enough to dislike the real Na Bong Seon. Love is happiness and sadness. :-( Ouch! My throat still hurts. The casts? Like always, Kim Seul Gi (Shin Sun Ae) is hilarious that I always watch the dramas she's in. She's not pretty as doll but her funny personality is enough to make you like her. Park Bo Young (Na Bong Seon) is surprisingly energetic and cute. I didn't see it coming because she was serious in other dramas and movies. However, her voice is annoyingly loud. Jo Jung Suk (Kang Seon Woo), on the other hand, is a natural actor. I didn't swoon all over him, and I can't see myself doing so in the future, but he truly did a great job here. He earned my respect. Overall, that was a bunch of amazingly brilliant actors! The OST? Actually, I neither remember how those sounded nor I care. I won't rewatch this. Somehow, "49 Days" and "Oh My Ghost" are similar; although, the first one is melodramatic while the latter is more comedic. Overall Rating: 7.5/10
