Headcanon that, after the finals, Victor and Yuuri notice that Yurio is on his phone a lot (and SMILING AT THE SCREEN!) and - after some snooping - they discover that he’s texting back and forth with Otabek.
Victor: He’s too old for you!
Yuuri: Victor, they’re not even three years apart. It’s less than our age diff-
Victor: Alright, but he needs to come by the house so we can meet him properly.
Yuuri: We already know him.
Victor: We know him as Otabek Altin the skater, not Otabek Altin our son’s boyfriend.
Yuuri: Well, maybe we can invite him to Yu-topia for a long weekend?
On Yurio’s phone:
Otabek: Are you okay? That last text looked like you mashed the keyboard.
Yurio: I’m fine.
Yurio: Have you ever had katsudon?
They’re not dating (yet - Yurio is more concerned with finding himself and feeling comfortable in his own skin) but he wouldn’t mind his good friend coming to visit.
