Fudanshi Shoukan: Isekai de Shinjuu ni Hameraremashita Mini Anime

A brief anime celebrates the second volume of a BL manga. Kotone is a fudanshi who is killed while purchasing BL manga outside a stand, struck by an out-of-control truck covered in the material. He awakens in an ancient-style Asian palace. A half-serpent named Nagi informs him he is now Nagi’s Miko. For Nagi to evolve into a Dragon, they must have sex. Kotone, well-versed in BL, recognizes his role as the bottom. He intends to use his knowledge to avoid falling in love and to prevent being the bottom in this Isekai setting.
