Goh Akazaki is a 26-year-old man... who happens to be a shojo manga artist. His assistant is Yusuke Akune, who happens to be a mangaka in his own right. But when Goh accidentally finds out that Yusuke is gay, he's thrown for a loop—what else about his friend doesn't he know? And when Goh is asked to draw BL, he tries to pry into Yusuke's experiences for inspiration... but when he is ultimately inspired by the idea of "unrequited love for Yusuke," can he keep his own feelings out of the mix?
