And hears arguing

Getting to the training ground Naruto heard yelling, back and forth, a rather heated argument. He instinctively hid, speeding to a tree far too fast for anyone else to see, and flipped between the trees, completely unseen.

Towards the center was Sarada and her boyfriend Boruto, both red faced and shouting. Now closer he could tell the argument wasn't about much in of itself, but just a lot of tension over a lot of things. Boruto being inconsiderate and always complaining, Sarada prioritizing being a ninja and not always being on the boys side.

Naruto sat down and relaxed, content to watch for the moment, he had nowhere to be yet and despite his son being there Sarada still looked amazing in her form fitting workout clothes.

He figured, them being teens and emotions running wild, there was about a 1/3 chance of them just walking away in a huff, 1/3 of them finally breaking up after all the tension they had had in the last few months since getting together, and 1/3 of just fucking it out.

And Naruto was in place to react, or watch, or just walk away. Whatever he wanted.
