It truly is something special that a polyship got popular enough to make Tumblr's top 100 ships, especially since that polyam representation and recognition are sorely lacking in media and in fandom.
Even for all of the great strides made in onscreen queer relationships, you'll find that polyam relationships get nowhere near enough representation, recognition, and respect.
That's why Deltarune Chapters 3 and 4 were such a huge deal for polyam rep, especially since one of its characters actually formed a polycule: Rouxls Kaard with Elnina and Lanino. Even though the Weatherkaard polycule didn't quite work out, it was still a huge deal in raising awareness and acceptance of polyam relationships, which in turn led to Krusielle's surge in popularity.
Even though, at first glance, the plot mainly focuses on Susie's romance with Noelle, it's also clear that the two girls share a strong bond and an extremely deep connection with Kris, so much so that some have even speculated and argued that Noelle and Susie will end up forming in a romantic relationship with Kris (or at very least a queerplatonic relationship as others argue that Kris is aroace/aromantic)!
So yeah, whether you ship Krusielle or not, you can't deny that it means a whole lot for polyam representation!!!
