Lolig's manga / #fudanshi(3)

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!

Kanata, a Fudanshi repeating his university exams, is in love with a seme character of a certain BL manga, Seijurou. One day, a super hot guy, Seiichi, who looks exactly like Seijurou, appears, and happens to be his private tutor! And he said that if Kanata meets the conditions, he'll become his personal boyfriend?!

Pretty good. Story of a fudanshi finding out his identity with a one Shot with switching? Unexpected uke for the one Shot
