The major thing that I disliked the most was probably the story. Everything happened way too quickly at the very start of the series. The whole 'curse' was thrown at us so unexpectedly that I didn't even take it seriously. I think the best decision that the writers could have made to improve the story was to go more in-depth to either the whole 'curse' of the school or stick to the school's strict guidelines and follow Ayan's uncle's story. With this in mind, the plot would be a lot more different, but I think that for ME to fully enjoy 100% of this series they would need to either take out the whole curse or fully develop it and make it more enjoyable to watch. Overall I think the series is interesting to watch and the chemistry between the characters is wonderful. Would I choose to re-watch it? Yes, yes I would.
