Miyano is a high school student with a secret–he's a BL fanboy. He's passionate about his hobby but doesn't share it with others easily, until a chance encounter with a quirky sempai named Sasaki brings a new friendship. Sasaki doesn't know what the heck a 'seme' or 'uke' is, or why he should be worried when Miyano threatens to draw doujinshi involving him, but he's eager to learn about his cute new friend's hobby!
