This story is about two boys (i know what your thinking 'two boys is this yaoi(boy x boy)' well yes, yes it is) who grew up together in the same neighborhood since they were children. But one day on Natsume's birthday, Natsume doesn't show up at school. Actually, he doesn't show up for four days due to a 'cold'. Natsume's best friend Rin decides to go check up on him to see whether or not this is just a cold. When he gets there he finds that Natsume isn't what he has seemed to be all those years they spent together. What will happen? Will they stay as friends or will they become something more? Or will this secret that Natsume has keeped from Rin rip them apart? Hell if i know, i just wright as i go will find out together as the story goes on. XD
