wait, their wedding isn't canon yet? :(
I’m sure they will get married one day, but that picture may not be how it plays out - that’s just Sunati imagining.
Possibly one day I’ll work out exactly how their wedding will go and draw it out, but I don’t think they’ll get married for at least another five years, and I’m not yet sure what sort of wedding Sunati and Austen will want when they’re older. I’ll have to wait for them to tell me :)
