Compare sakuras screentime with sasukes screentime in part 2. The first 50 chapters were without sasuke. in the next 50 we get to see him 1 time. then theres this short team taka arc. the next thing is itachi and summit. On all the other chapters we get to see sakura and naruto.
Maybe sasuke has bigger fights, but in screentime sakura is still on the lead.
Yeah its right that sasuke is a big part of the manga, but that doesnt mean that hes the main protoganist.
If this is the conclusion you come to from reading the manga, I don't view my chances of convincing you otherwise very good. So when is the last time Sakura had a big fight? As in fight that lasted for several chapters. Sasuke's was with Itachi and Kabuto earlier this year, and that wasn't even the one he was the most prominent in. His previous one was the one with Danzou, then the one with Itachi then the one with Deidara then the one with Naruto. How about Sakura? Sasuke can disappear for ages and during that time Naruto has time to sit around remembering his kiss with Sasuke, to hear his mom remember how she met baby Sasuke and promise Itachi to look after Sasuke. When was the last time we saw Naruto think about Sakura when she wasn't around?
Swagosaurus, sure, she might move on from Sasuke. We don't really know yet. So far Sakura's love for Sasuke has outlasted 3 murder attemps. Maybe it will last all the way till the end of this manga.
Anyway, that's it for me for tonight. Merry Christmas.
