Salaryman Kirishima has been friends with Toudou for years, since college, and now they're working together. Kirishima is a big brocon and is super overprotective, so when he suspects Toudou (who he's know was gay from the beginning) is making the moves on his brother he's willing to do anything to protect him, even take his brother's place. It's pretty obvious that Toudou has an unrequited love for Kirishima, and that Kirishima is misunderstanding the situation. Very nice art style, I love a glasses seme!
Renai Nante Yurushimasen!
