This was for sure a great read, so fun and brought on a bunch of feels, but ugh, such a bittersweet ending. It felt like 20 chapters of just pure misery at the end, not because I thought it was bad, just the slow roll toward the inevitable. Would have been really satisfying to see what would happen if they had let her suck his blood in the end, maybe it could have turned out differently from Mahiru and Kiku, since both MCs were unique beings. I think that would have left a different kind of bitter aftertaste though, having the 14 year old end up with the 40 year old.
