i definitely enjoyed the opening theme song first of all. got me all hyped up to watch this. the overall aesthetic and settings were nice as well. just dark and mysterious. as obvious as the title, this was full of religious imagery and teachings. i loved the fact that both of them had different major. one specialising in ancient manuscripts and the other in science. a very great combination. we already witnessed a huge tragedy just from the first episode. it was a good start considering how intense the situation was.
