Kotone is a hardcore fudanshi whose entire life revolves around reading and collecting boys love manga. While purchasing the latest romance volumes from a street kiosk, he is tragically struck by a runaway truck and perishes buried beneath stacks of manga. Reincarnating into a mystical ancient realm, Kotone is astonished to learn that he was magically summoned by Nagi, a magnificent divine serpent beast. Rather than a fierce battle asset, Nagi desires Kotone as his destined sacred consort. Caught in a whirlwind of supernatural romance, the delighted fudanshi experiences his favorite fiction tropes firsthand.
