While this is not a novel arrangement, Mikoto had thought he was invited solely to play sports. To make matters worse, he is forced to compete in doubles despite his reluctance. Struggling to adjust to his new professional life, Mikoto begins to doubt his decision to join the company. However, as he learns more about his latest teammates, he might just find the strength necessary to advance his badminton career.
