Well to be fair, I said I’d once heard that Kaoru was divorced, but I heard that from a foreigner, so I take that with a healthy dose of skepticism. The last time I looked at a recent (I think?) Dir thread, they seemed to think that Kaoru was married, but that if he doesn’t have kids soon, he’s going to end up becoming a father in his late 40’s like Imai from B-T.
I’ve never seen anything specific about Toshiya being involved with anyone. The impression I’ve gotten is that he is enjoying his fair share of teh pussay before settling down with someone.
