First, "nekopoi" might be a misspelling or a mix of "nekko" (cat in Japanese) and "poison," but I think "Nekopoi" could refer to a Japanese animation or a style. Then "onaseyunnooneloversherpremium" – perhaps a combination of "one scene" and "lovers her premium." Maybe the user meant to write a story about a premium scene involving a cat-themed character (like a neko girl) in a romantic or premium (exclusive) setting.
