The world that I once knew

In a world that is almost like ours, yet so different, there lived a person who fights to find the person who killed his parents, and finds a person to where he could start over again. But, can he bring himself to start over and forget about the people who killed and destroyed the only thing he could call a family and happiness? While he attempts to decide what he has to do, the person who loves him Zero has to go through his own challenges of freeing himself from his "Masters" and getting to run away with his lover. But he still cant get his lover to forget about his past and move on with him. Thus is a story where two lover (aka guys) try to live a life together, but their lives and troubles are dragging them down and taking each other apart.
