Happy Tennis

Jeff has been called the 'future star of tennis' from when he was young. However, after a traumatic loss in his childhood, it seems impossible for him to win ever since.
Even though he has mastered all of the techniques- serve, smash, volley, footwork- the goal of victory always seems distant.
Tennis is supposed to be about the enjoying the game, not the result. But will Jeff ever overcome his habit of losing at the crucial moment, and achieve victory? (Source: Manga Fox)
