User blog comment:Tounami/Who do you think Endou's going to be married to?/@comment-4091102-20110629221719

I just had another Idea why Natsumi could be Endous wife. It would fit to the story of GO.

I think Endou will defenetely go against the orders of the fifth sector and the principal would fire him. But if Natsumi or her father (Endous father in law) is (still) chairman of Raimon, he simple can't do it, because the chairman won't allow it.

That seems really good to me.
