This was super sweet and wholesome! The artwork and voice acting are top-notch (my favorite visual is definitely the VHS title screen), the story was really cute, and the relationship between Sada and Kou was well fleshed out. I could definitely see this being a supernatural/slice-of-life/romance type anime in the vein of Hanako-kun or something. Wish we got to see a sprite for Kou, but in my head I just pictured a younger Reigen Arataka which suffices too :3
