This is a touching story of sincere affection between a dependable senior self-defense officer and a dutiful young man. Mamoru, who joined as a self-defense officer at a young age, has always nurtured deep feelings for his superior, Akutagawa, who once came to his aid during their time in high school. Mamoru finally finds a chance to work side by side with Akutagawa when he is posted to the same base as him. As he was unable to confess his love to Akutagawa in high school, Mamoru takes the opportunity to express his feelings plainly, saying, "I'm a mature man now, so please notice me." Mamoru doggedly pursues his love, but will he ever succeed in his pursuits?
