Ren was found wandering around Japan and taken into an Orphanage. When he was found he only knew his name and age but nothing else. Once at the orphanage he was abused and withdrew from society (he acted like part of the wolf/dog pack) and Haru's parent's adopted him but they died in a car accident. Also, Haru is the one who got Ren to be "normal" again... hope this helps!

What happened to Ren's parents again? Guys please refresh my memory.
