Things Sasuke has done today:
Sat in class and minded his damn business
Had Naruto get in his face which ended in their lips touching because an absolute icon was sitting in front of them
Called Naruto an idiot for that but didn't even subsequently try to hurt him (unlike Sakura)
Is currently eating lunch and continuing to mind his damn business (and will shortly be attacked by Naruto)
And as usual I'm not so much saying that this plotline shouldn't have happened so much as Kishimoto has a lot of gall to write this without any reflection on Naruto whether that is the character self-reflecting or someone else pointing out that Naruto was the problem here because Naruto was 100% the problem so it's funny that apparently at the end of the chapter this was about Sakura learning a lesson.
