You know, I've been floating around the Sasuke/Hinata tag for longer than I'd probably admit, and the emotional growth stuff is always a tricky needle to thread. A lot of early fics just sort of...force it? Like, they'd throw them together post-war and have Sasuke do a complete 180 overnight because Hinata made him rice balls. It felt more like a character transplant than growth.
What works better for me now are the fics that treat his healing like a jagged, non-linear process. There's this one story where Hinata's quiet persistence isn't about fixing him, but about being a consistent, non-judgmental presence while he fumbles through relearning how to connect. Her growth is often about finding a voice that's assertive but not aggressive, which can be hard to write without making her OOC. The best arcs make their development parallel—his outward journey to atone mirroring her internal journey to step out of passive patterns. It's less romance driving change and more two damaged people accidentally inspiring it in each other through awkward, mundane interactions.
Honestly, the ones that fail are usually the ones where the author is more in love with the 'idea' of the ship than the actual characters.
