I was really hesitant to watch this at first because I'm not really into fantasy stories but since it's gong yoo I gave it a shot and boy did I tell you I regret it? This is so good that I could re-watch it again if it wasn't for the long list of other K-dramas I must watch. Grim reaper and goblin's bromance is undeniably adorable. Kim go-eun's acting is perfect I cried with her.
