Baby Steps follows Eiichirou Maruo, a diligent honor student who decides to use his limited free time to get healthier after spotting a flyer for the Southern Tennis Club at the start of his freshman year. What begins as a practical choice quickly becomes a challenge that fits his strengths: he watches carefully, remembers details, and approaches every drill with a perfectionist mindset.
At the club, he meets Natsu Takasaki, a first-year student who dreams of becoming a professional tennis player. Her ambition gives Eiichirou a clear point of comparison, but his own growth comes from building patience and discipline rather than relying on natural talent. As he learns the basics of the sport and starts to understand how each small adjustment can change a match, he slowly develops a style of his own.
Baby Steps tracks Eiichirou's progress from complete beginner to serious competitor, following the daily grind of practice, observation, and adaptation that pushes him toward the best players in tennis. The series highlights how improvement comes from repetition, focus, and the willingness to learn from every point, while keeping rivalry and determination at the center of its sports drama.
