Man, I've been down so many 'Konoha wants Naruto back' rabbit holes. The most obvious theme is massive, crushing guilt—you get these long scenes of Tsunade staring at paperwork about Naruto's accomplishments, Kakashi rereading the Bingo Book entry, civilians realizing they cheered for a kid who never had a single friend. It's like the whole village gets hit with a collective panic attack. They treated him like a monster until he became strong enough to be useful somewhere else, and now they have to sit with that.
But the flip side, the one I find way more interesting, is Naruto's own emotional arc. It's rarely simple forgiveness. Sometimes he's just bone-tired, unwilling to play the hero for people who hurt him. Other times there's this cold, calculating anger that feels so unlike the original character, but makes a weird sense. He's learned he can build a family elsewhere, so Konoha's desperation feels pathetic, even insulting. The best fics make you question if he should go back, even when they're begging.
A lot of them also sneak in this theme of legacy and ownership—like, Konoha feels they own the 'Will of Fire' and therefore own Naruto himself. His defiance isn't just personal; it's a rejection of their entire system. That political layer gives the emotional stuff more weight, I think.
