Like many other viewers, I am confused by the last episode, 61. Was the intent of the last scenes meant for viewers to see it as 2 different endings? If so, then 1 ending actually ends when XX swims to BYY and they meet, assuming both is dead now and they both progressed to afterlife where XX is there greet her. Last bit of that scene fades to black, which to me means, the end.
The other ending starts with her crouching and crying at the bridge and XX walks up behind her and they meet, and hug and its a happy ending. But there are so many unexplained ploth holes around how XX could've survived. These plot holes needs to be explained if the director want to convince me that the story can have a happy ending. For example, the scene when XX finally dissapates the evil spirits and purifies the pagoda, we see Leng Chu uses his buddah power totem to suck the clean purity aura into his totem pole and he also sucks all the water dry. Did he use the purified aura and magic water to bring XX back to life? was this how XX was able to surive and needed 7 days to recover and this was why XX was late to meet BYY at the bridge? See, this is what we, as viewers, need to see in order for us to 'fill in the gap' to understand why XX can survive and meet BYY for a happy ending.

Just my thoughts, but did enjoyed the series. Also its my first C drama ever, so I'm probably bias.
