Props to the author for how they wrote the father in this chapter. The vast (and I mean overwhelming) majority of other authors, would just make the father a two dimensional bad guy, with negative opinions about lesbians. A punching bag for the main characters to lecture and berate; after he showed how cruel he was. Instead, the father had legitimate and practical concerns for his daughter's well being. Those concerns were discussed and addressed. And the father treated Elsa with respect.
Literally every other time I've seen a similar where situation where two lesbians are meeting the parent in fiction, it's either the dad is evil and just hates lesbians for no reason, or the parents have zero issues and are perfectly happy. Those are the only two things I've ever seen depicted. So for the author to show nuance, and actual discussion, without resorting to a cheap stereotype villain, was refreshing.
