I never imagined that a show about ghosts, the afterlife and darker themes would be so incredibly heartwarming. This is an amazing example of how to take tropes that have been done time and time again and transform it into something new and exciting(plus P.O is a great bonus haha). You can tell this show had a higher budget - the location atmospheres are so incredibly captivating and visually stunning, the story is well done with little -if any- room for improvement, and the cast (despite having 2 idols which is normally look down upon) is also simply amazing. There is a great diversity in character archetypes which I personally belive isn't seen much is many dramas - it isn't just a strong female lead but the background characters are also unique and something rarely seen!!
