Admired by the quarrelsome duo, Wakaba often finds herself the catalyst to their never-ending rivalry. But whether or not they realize that they have more in common than either would care to admit, only time will tell. The game of baseball may just be what the pair needs to ultimately overcome their own personal struggles. [Written by MAL Rewrite]
