Man Who Defies the World of BL, Vol. 4

What would you do if you suddenly realized you were living in the world of boys' love?! Could you avoid the tropes?"I'm aware, y'know. I know I'm a character in a manga world. And not just any manga world either. This one is boys' love."Our straight-as-an-arrow protagonist has grown quite accustomed to the BL world he's found himself living in, even enjoying college life to the fullest! Every now and then he gets the urge to let his guard down just a little. But he still manages to successfully maintain his role as nothing more than a background character bobbing and weaving through the BL flags springing up around him-that is, until a fleet-footed BL flag appears!
