All of their dreams to stay together come crashing down, however, when Aoi is forced to participate in daily obscenities with the physical education teacher, Shoda. With each day, she comes to realize that she enjoys it more and more. Even after powerless Akito discovers the truth, Aoi shows him just how much she wants Shoda instead.
