Youichi Nanase has a huge problem. His adorable little brother attends an all boys’ school - one that is rumored to have a 90% gay student population! Fearful for his brother’s “safety,” Youichi spends his nights drinking his woes away with his coworker, Renji Tsutsumi. But Youichi’s brother isn’t being pursued by his classmates; he’s the one doing the chasing and he’s finally captured the heart of his volleyba;; teammate. Poor Youichi is at a loss for what to do. His own kid brother is gay? And he’s spending nights at his boyfriend’s house?! To make matters worse, Renji himself has fallen deeply for Youichi. But due to Youichi’s strong anti-gay sentiments, he is afraid to confess his feelings. When binge drinking leads to a heated exchange of kisses, Renji finds himself falling deeper and deeper for Youichi’s charms. And Youichi starts to wonder if “being gay” might just run in the family.
