Best girl arrived, why the mangakas almost always do a better background/premise for a main female character with a side girl is beyond me. This is a perfect plot for a funny and cute romcom manga about two bloodlusted (bad pun i know) protagonists and how they overcome their "curse" together but no we need more generic boring premise of love at first sight and misunderstandings (with probably flashbacks later in the story to make it seem it was planned).
