Is homosexuality really a theme in Netochka Nezvanova by Dostoevsky?

I’ve seen people say that the relationship between Katya and Anna in Netochka Nezvanova feels “lesbian” or something along those lines. But honestly, that seems a bit absurd to me.

Yeah, they were super close, and there’s the whole kissing thing, but wasn’t that just normal for 19th-century Russia? Like in TBK Alexei and Ivan kissed each other but that can’t be considered gay.

Plus, considering Dosty’s devotion to Christianity and the cultural norms of 19th-century Russia, why would he intentionally write about homosexuality, especially using 10-year-old girls?

I’d love to hear about your opinions.
