Chouji's conversation with his father being the most overt, (Chouji outright says something along the lines of: Not everyone starts a family young, meaning he's ruled out for being first, but if his pretty likely partner is Ino, and Sakura and Naruto get together soon, count on them being second, remember Asuma's final words to Ino about not losing in love in competition with Sakura, it wasn't about chasing the same guy, but getting together with the guy she actually loves, and you know Asuma knew it was Chouji and knew that Chouji loved Ino but felt too intimidated to make that first move ....
I'm betting they'll be the only young couples, Kishimoto made it pretty clear Shikamaru and Temari will wait, and the other couples just haven't been developed enough to make them anywhere even hinting toward certain. He's kind of playing around with Hinata, hinting a bit with Kiba, then a bit with Neiji, I'm guessing KibaxHinata and NeijixTenten at the end though. Also GaaraxMatsuri (fairly certain but left as very minimally developed because Matsuri is only a very minor character) but again that likely won't show up until the typical epilogue timeskip chapter.
There are subtle hints even as far back Chiyo's final conversation with Sakura where Chiyo emphasizes to Sakura how much like her she is. It's dominantly about Sakura's personality, but Chiyo says enough to show it's also about her choices, including romantic ones... That context comes out more as Kishimoto builds in other romantic parallels for Sakura and Naruto. Kishimoto does this a lot, you see a scene have an obvious context when it happens, but later you see there are more subtle ones that connect to later scenes....
Chiyo is one of the two known kunoichi that had her first child at or before she turned 18. The other is Tsume, Kiba and Hana's mother, she gave birth to Hana 4 months before she turned 18, meaning she got pregnant just before she turned 17. Chiyo died at 73, her grandson Sasori was 35, the picture of her son and his wife with infant Sasori are of a couple in their early 20's.... so the math works out at the oldest Chiyo was 18, but she could have been as young as 16 when she became a mother. (Sakura has just recently turned 17...)
