I always find it sad that everyone finds love and moves on, but Asgore is always left in the cold. From in -game dialog with Toriel, it is clear that he moved on from her as well (he just wants to be friends). Yet, so many folks do stories where Toriel finds new love but Asgore must suffer alone (which is sad, given she is as guilty as he is for the exact same reasons). I just wish more folks would let the big guy find a new love too. Maybe Muffet or Grillby.
tbh I think it’s mostly because people wanna ship Toriel with someone, rather than actively shutting the old man out. Toriel’s also got some in-game moments with Sans that make them prime shipping material. meanwhile, Asgore doesn’t really have any potential ships aside from crack ships.
Personally, I’m a big fan of Asgore/my-own-interpretation-of-Gaster. They must’ve known each other in the past, and if canon Gaster is even half as soft and kind and well-meaning as I write him, then I absolutely think the two of them would be amazing together. I really love the idea of these two sad old dads, who have been through so much, finding each other and settling down and improving each other’s lives just by existing near each other, it’s such a happy-feels-inducing ship.
Just gotta fish Gaster out of the void and put him back together again first. it ain’t no prob
