Only a Matter of Time

Shortly after his third year at Sobu High begins, Hachiman finds out that he is terminally ill. While the others are moving on to the next stage in life, he's moving on to the final stage of his. How will this affect him and everyone around him? This is my first fanfic and I really love the series, so here goes. Note: I started this between the release of Volumes 11 and 12.
