Angsty headcanon for season two/fanfiction: What if Yuri gets jealous of Otabek’s other friends?
Yuri must have some abandonment issues. I get the feeling either his father left when he was young or was just never in his life at all. And his mother, being an ex-idol, maybe she wasn’t involved and ignored him a lot until the time came where she just up and left, leaving Yuri to be raised entirely by Nikolai.
So since Otabek has a lot of good buddies back in Almaty, it seems natural that Yuri would get jealous. He’d want to be Otabek’s best friend.
But it’s okay because Otabek would rather be lovers than just friends.
