Shiro and hiro are childhood friends.. They're really close. Shiro is a serious and dependable guy. Hiro is a slob who can't do anything without shiro.
Shiro felt the urge to hurt hiro one day and he's been hating himself since. I feel that hiro secretly likes the abuse.
Shiro ran away once he's gotten into college and got himself a girlfriend. Poor gf..
But hiro doesn't go away. Shiro kept thinking about hiro and his hurt face. In the end they met. They csn never let go of each other..
