About a guardian spirit, Soou, who falls in love with a 20-year-old college student named Naoki. First Soou tries to reach her on the physical plane and asks her to come with him (presumably to the astral plane, where he lives, but he's too lost in romantic fluff to tell her and she's too drunk to understand), but she throws a fit. So he pulls her through to the astral plane by force, but her guardian Nusaka yanks her away from him and reads him the riot act. So as a last resort, Soou follows the girl back to the physical plane to guard her close-up and personal. "Guarding her up close and personal" means living with her, and living with her means pitching in, so Soou and Nusaka don aprons and start cooking.
