Yaoi that have very raw characters and realistic scenarios are pretty hard to find. This is a list i want to fill with such stories for people who love realism in manga just as much as i do. However: realism does NOT necessarily represent quality. The art may not be great, but the story will 100% be.
Also:The manga may not always have raw characters and well developed personalities, but they may have those moments of realism that a lot of yaoi fails to include.
