Nodoka's married to Genma.  She can't get involved with Soun...oh 

wait you

meant pair the two up with _different_ people.  Well, Soun's still 

greving

over his wife (everyone says that she died, but I don't remember it 

ever

being brought up in the manga.  _Is_ there any evidence that Mrs 

Tendo is

dead, besides the fact that she's not there?) and Nodoka is married 

to

Genma, of course I have seen a fanfic where Soun gets together with 

Ms.

Hinako...

I know there's evidence of it in the anime: in an early episode, 
Kasumi tells Akane: "Listen to me as though I were our dear departed 
mother", and in Movie 2, Akane says to Touma "So you lost your mother 
too?"

Oh, and let's not forget the OAV concerning Mother Tendou's notebook..
