"Please marry me!" As school nurse Isshiki reminisces about a frail, beautiful boy who was once bullied and whom he had helped, a muscular new physical education teacher, Morikawa, appears before him. Upon closer inspection, he was indeed that beautiful young man, and what's more, he proposed to me immediately upon our reunion!? Will the day ever come when Morikawa, who uses every trick in the book and relentlessly pursues Isshiki despite his repeated rejections, finally succumbs to his unwillingness to say yes...? I never imagined that such a pretty boy would turn into such a tenacious macho man! A romantic comedy about the battle of wits between a devoted gym teacher who was once a student and a scummy, troubled school nurse!

The story begins with Uta, the unlucky protagonist, suddenly getting close to Chief Morino, who is big in both mind and body.
