Nobody in the manga wears a wedding ring, not even MinaIKushi.
It still doesn't excuse SasuSaku. Kishi just sucks at romance. I was told that his wife was the one that helped, though not involved, planned the MinaKushi romance and admitted a women assistant help guide him and Yahagi through chap. 181 (which had SS romantic undertones). My guess is that he had female assistants that helped him through romance, but suddenly dropped and he was left with just putting them together.
After all the interviews, I can say that Kishi doesn't care about Naruto.
But I can also say that he really doesn't give a damn about any paring except SasuNaruSasu.
SNS is the only paring where he admitted that he wanted both Sasuke and Naruto to hold hands at the end of their fight, but his editors told him that it needed to be gory, which is why their arms are cut off. And SNS are the first paring to get a drama CD dedicated to SasuNaru in a way. Then you have Bolt movie which Kishi wrote, and look at the SNS fanservice. I really believe that Kishi ships this couple or just favors it because I never seen him so dedicated to any couple other than SNS. I would say NS as second, but then you have the 5 Kage and War Arc, and Kishi "forgetting" Sakura, so I'm still on the fence. I know he supported NS at the beginning, but not in a way that one would believe he would care about.
I believe he thought NS, SS, and NH all the same and he would definitely sideline NaruSaku/SasuKarin like he did to SS/NH for the sake of SasuNaru. In Gaiden, Sasuke had only contacted Naruto and vice versa for Naruto to Sasuke on the Boruto movie. They are more connected to each other than their wives and the way it happened, I had a inner feeling that it would have happen to NaruSaku as well, and I don't like it at all. I understand how SNS is important but just like Hinata, it made no sense to the plot. Mainly because just like SS, SNS was also onesided.
I remember the Kishi interview with a lengedary mangaka (he created the NS and JiraTsun art) where he called out his obsession for SNS and Sasuke, even though it was very much onesided. Kishi defend himself though, which is why I believe he's a secret SNS shipper...
