High-school student Shouta Tanaka is struggling with a secret: his hair has been thinning for years, and he is going bald. He worries about how his classmates will react and what it might mean for his future. Afraid that his crush, Shinohara Ami, might discover the problem, he cannot bring himself to ask her out, or to tell his family and best friend, Sachio. When his clumsy biology teacher, Mai, offers to find a cure, Shouta is skeptical and tries to avoid her. But as his hair loss worsens, he turns to Mai as a last resort, hoping she can solve his problem.
