This, marriage isn't really a theme that Kishi likes to focus on. When he does mention side characters from Naruto's class, we only know about at most one parent for each person. For example Shikamaru and his dad Shikaku are both featured in the story, but Shikaku's wife isn't. We know she exists though because he's referenced that she wears the pants in their marriage.Well... You can assume a lot of people are married. But no, they don't really talk about marriage a lot. I don't think Kishi is a fan of romance~~
actually i just saw shikamarus mom 3 episodes ago (im rewatching part one) in episode 100 something when they are about to go after sasuke and shikamaru and his dad are eating breakfast and his mom is nagging them, then he asks his dad why he married such a grouchy woman. then the door is knocked on and she answers the door. then you had both of sasukes parents as well when they were alive.This, marriage isn't really a theme that Kishi likes to focus on.

Hell, it took 500 chapters to figure out who Third's wife was and how she died. Kishi never had him mention her once though because she wasn't important at the time
