I feel like Nanami AND Gojo are such caretakers to each other post canon(the good end)
Gojo quits sorcerery but doesn't stop working with the kids. (imo in this "good" end, Gojo makes a binding vow to 'give up' the Six Eyes in order to save his kids but sitll takes the brunt of the WCS damage). He still teaches them and shows them what he can. I imagine after everything, in the absence of being overstimulated, he's under stimulated. There's always something missing until he sees his husband.
Kento also quits, as much as he wants to keep helping, he can't. In his version, he did get burnt by Jogo but stays passed out for longer, so Mahito doesn't happen--with the caveat of him loosing his arm and scarring on the burned side(so nerve damage!).
And they take care of each other! In th aftermath both of them are in comas(either medically induced or otherwise), but Gojo wakes up first. He wakes up and the first thing he does before he's even cleared to get up is ask where Nanami is. In the days that come before Nanami's awakening, Gojo spends them by his bedside, talking to him and bringing his favorite breads to "share"(he likes to think nanami eats them in spirirt).
They both grieve the part of themselves they lost. Gojo has a hard time walking due to the WCS causing some spinal injuries. Nanami opts to not have a prosthetic fitted, there wasn't much left to attach it on(shoulder disarticulation) but has a hard time adjusting to.. everything.
But they manage.
After so long of Gojo having to take care(or more accurately not doing so) of himself for so long Nanami notices all the times he comes home tired. Has a warm meal at home whenever possible, providing acts of kindness and silent affection since he isn't really the most vocally articulate with his feelings. Gojo also helps out where he can! He cuts veggies for him and more often then not finds himself buttoning Nanami's shirts for him
more to come but im just drabbling
