Twilight Cure Important

Ryo works as a bartender at a gay bar. In a place where emotions of lust ran rampant, he is an outlier known for already being 'dried up' or impotent, which isn't the case. Ryo isn't just interested anymore. Enter Umezaki, Ryo's friend from college and his ex 'friends with benefits' buddy. Contrary to Ryo, Umezaki is a well-known playboy and flaunts his sex skills to anyone interested. But when Umezaki starts showing symptoms of impotence, it's Ryo who he turns to ask for help, much to the latter's frustration since Ryo still has feelings for Umezaki.
