this drama started off really good, it was intriguing and full of things that I was excited to see how it unfolds. the combination of sageuk and fantasy (devil, god) for me was really good, cause it's new to me and so i look forward for every next episodes. but sadly that only stays for up until the first half. the second half it went downfall, it is full of repetitions andI can't even remember what happened for those episodes cause nothing was actually happening except for 1 or 2. and most unfortunate is the ending, idky the writer rushed every single thing to be concluded in ep16. the ending was meh except for the couple of course. like, after all those intriguing, we need to seal the demon forever, sacred vessel, it only ends like that? and of course, prince joohyang's story also doesn't end (well).
