This was the episode that finally brought me on board - somehow with this episode, the drama went from pretty and entertaining but uninvolving, to frelling gorgeous and emotionally resonant.
First, the scenes in the afterlife are amazing and inventive and quite like nothing else in a drama.
( Some scenes from there )
But what really got me wasn't even that inventiveness but the fact that I finally felt connected to Eun Oh, Lee Jun Ki's character. His quiet grief really got me. But not as much as the scene where he goes to conduct her funeral, only to discover her not in hell or dead but in front of him, made human again.
( Scene of amazingness here )
I am not emotionally invested in Arang yet because she is a period kdrama take on a manic pixie dream girl (same thing she was in Gumiho, really) and it's not my sort of a trope (I am entertained by her, but not emotionally invested), but I don't need to be emotionally invested in both leads - one will do.
Oh, and my money about the murder mystery is that JW killed her, without knowing who she was, probably on the bidding of that mysterious figure in the preview. And I do think EO's mom was somehow involved.
