Twelve years ago, when Ryou was chosen as the snake god's bride, he greeted his wedding day with utter excitement. After all, Ryou was a die-hard non-human otaku. His immediate interest lay in the snake god's lower half, rumoured to have two appendages. If he's a giant serpent, surely that part must be enormous too!? he wondered, utterly fascinated. But when the first night finally arrived... nothing happened at all?! It turns out the Serpent God has a secret! The intimidating Serpent God wants to do that, but he also wants to love! Pure romantic feelings vs. a runaway lower body! What fate awaits this agonisingly sweet non-human marriage!?
