I don't want to make this review too long so I will just make a quick review. A couple of fillers at the start of each episode. They were effective as it reminded me of events that happened. It also took me a couple of episodes to settle into the story properly but by the 7th/8th episode, I was definitely hooked. I''m glad that I didn't drop or put this kdrama on hold. The best episodes IMO are from episode 9 onwards. The story was really well put together. Even though I didn't really know much about how goblins and grim reapers work in this kdrama, I got to learn some things.. The bromance between the two male leads was great! HAha definitely one of the best in kdrama, no doubt. The acting was another outstanding aspect of this kdrama! Gong Yoo is such an amazing actor. I remember seeing my first work of his in Train to Busan. I always found him to be an amazing actor. Dong Wook was someone who could deliver a specific emotion just like that. He has such an expressive face. When he was sad, I was sad too. I was moved by his acting the most. Lead actresses KGE and YIN played their parts exceptionally well as well. This whole kdrama was just ethereal. Finally, the music was SO BEAUTIFUL. I loved all the songs I heard. They played a great role in helping me feel the emotions as I, a viewer, should be feeling at particular scenes. If you don't want to watch this kdrama, at least give the OSTs a chance because they're absolute masterpieces. I would definitely rewatch this again one day when I have the time. I would probably skip some parts (like the fillers) but I'd definitely be in it for the funny scenes ^_^ BTW Sung Jae did well with his role. It bought some extra fun and ease to all those intense scenes. Overall, this kdrama is a 9.5 for me
