To his surprise, he wakes up in an Asian ancient-looking palace. A man named Nagi, that is half serpent, tells him that he is now his Miko. They need to have sex in order for Nagi to become a higher being and become a Dragon. Kotone knows everything about BL and he realizes that he will be the bottom. Kotone will use his knowledge of BL to not fall in love and not a bottom in this Isekai world.
