A frightened blue-eyed boy awakes in a dark room, chained to a wall with strange black markings brandishing his skin. He doesn't remember his name, how he got there, or anything about himself. When a boy approaches him claiming to be his twin brother, Yukio, the boy is transported to a hospital room where memories begin to awake within him... starting with his name: Rin. (YaoiFic)
