there is this small part in me that tends to imagine what it would be like for giyu and sanemi to end up in a relationship post war, where everything is the same as canon including the marks. it might not cross their minds in the beginning; they are too preoccupied with healing and falling in love, but after a year when it all settles down, and peace is their new reality, that is when the idea creeps into giyu's head and he recalls that meeting they had with amane in which she told them about the marks and their inevitable consequence. I wonder what giyu would feel then, the moment he realizes he might become another person sanemi is forced to lose. would he feel guilt over the momentary relief of knowing he will not have to outlive sanemi? would it sting nonetheless? they are heroes and warriors, after all, death has always been so near and imminent. he and sanemi were always content with that but somehow the idea of their mortality bothers him now, scares him even. is it selfish for him to want more time when the rest of the hashira did not even have any of it? I also think of sanemi in that situation, what about him? how would he feel about taking up giyu's finite and precious time on earth? would he revert to his old self and try to push the other away to keep him safe and happy with someone else who has more time, with someone who could keep giyu's name and legacy going? would a small part of him break knowing that he might have to say goodbye to someone else and would he think it might be easier to never love? I wonder if they will talk about it, fight about it and then leave to spare one another the pain and heartache or will they just never address it and allow themselves the company of the other, knowing that it will end badly? I wonder if they would deem the love of the other worth the sacrifice and future tears. would they grow closer knowing they don't have a lot of time? would they go all in and leave any hesitation behind as they dive deeper into the relationship, giving themselves the permission to fall completely and utterly even if that meant their complete devastation soon after? do they stay or do they go. does giyu step back and allow sanemi to become a father and spare him the pain or does sanemi do his best to make giyu despise him so he can let him go. or would they simply ignore the rules of reality and plunge into a certain sweet love because for once they earned it and for once they deserve to be irrational and young?
