Probably some kind of arranged marriage to preserve appearances.He most likely thinks of her as a friend or something but he's definitely not in love with her.I think Shinobu loved his brother since they were children and he tried to fill the void of not being able to tell him (because he, himself, couldn't accept it) by sleeping around.
Well, that cleared up things...thanks!
So, what does Shinobu think of his wife? I know it's no that important but I'm just really curious and confused. Also, what's the deal with sleeping with that other woman when he already has Mariko?
