Kou and Nazuna’s relationship is super adorable, but I think that made y’all assume that this was a “love story” when it’s actually about the healing that can come from temporarily escaping your normal reality.
There is something to be said (I read this in the comments of the last chapter somewhere) that this story is basically telling you to hurry up and go back to being a normal person already, but at least that’s a critique of the themes based on the actual information presented and not complaining about how the sexy vampire lady didn’t end up with the lost middle schooler…
