Fox Hime Zero is a story about an ordinary guy and a fox spirit. I thought the story was beautiful, and enjoyed it despite its short length. If you're looking for a cute slice-of-life story that you can read in one afternoon, feel free to give this a try. Just be aware that this VN lacks many quality-of-life features that modern VNs have. (Btw, I don't recommend the other version, Fox Hime, at all, as it's much worse.)
