This was really wonderful and... actually very sweet! I started off disliking Marimaite, but seeing the way her feelings towards Sitri changed through the story, I grew to like her more and more... there's this great atmosphere of dread throughout, and the way the tension between Marimaite and Sitri resolves by the end really surprised me in a good way...
Also just, Sitri is amazing and how could you NOT fall in love with her <3
