A Man Who Defies the World of BL manga volume 3 features story and art by Konkici.

It's a boys' love world, and he's just living in it! Our straight-as-an-arrow protagonist continues to adapt to the craziness around him, dodging every handsome guy who barrels his way. And even though he continually finds himself in unexpected situations, he somehow manages to maintain his status as a background character. But how long can his luck hold out in a world made for boys' love? At least there's progress in younger brother Ayato's budding romance to keep us entertained!
