"Boys on the Run" is a seinen manga series that delves into the life of Tanishi, a 25-year-old office worker who struggles with self-esteem, social awkwardness, and a lack of direction in life. Tanishi’s mundane existence is marked by his unrequited crush on a coworker, Chiharu, and his inability to connect with others.

Initially reluctant, Tanishi begins training, finding an outlet for his frustrations and a way to confront his insecurities.

The narrative explores Tanishi’s journey of self-discovery as he navigates the challenges of boxing, relationships, and personal growth. His interactions with Tanaka, who becomes both a rival and a mentor, push him to confront his weaknesses and redefine his sense of self-worth. Chiharu, the object of his affection, remains a central figure in his life, though their relationship is complicated by Tanishi’s lack of confidence and her own personal struggles. The story also introduces other characters, such as fellow boxers and coworkers, who provide additional layers to Tanishi’s evolving world.
