I can’t believe I have to write this post, but March is just around the corner and i trust like 3 people in this entire fandom so
Why Yurio’s birthday doesn’t give you an excuse to ship him with adults, the mini essay
From information learned from the creators, we know Yurio’s birthday is on March 1st. However, his birthday passing in the real world doesn’t age him in canon. This is actually shown really well in episode 9, which aired after Yuuri K’s birthday and everyone celebrated him turning 24, but since the date hadn’t passed in the show, he was still 23.
Only canon time and dates can affect characters. Things like birthdays are more of fun tidbits for the fans.
So until March first passes in canon, Yurio is still 15, ie a minor. Because you all love “the age of consent in Russia is 16″ line guess what he’s not sixteen.
But let’s say, for… some reason that canon time continues even in the real world, and Yurio does turn 16 on March first (five days from when I’m writing this). He will have literally just turned 16. And I’m speaking as a minor here- the entire “well he’s legal now/wait until he’s legal” thing you guys have going on severely creeps me out. He was a minor the day before. One day doesn’t magically give him the full rational brain of an adult.
Just because he’s 16 and it’s legal doesn’t mean it would be okay for adults to date him, especially if they knew him as a minor
In conclusion (tldr)- only canon can age characters, so yurio is frozen in his age as 15 sometime in December. Even if he was turning 16, using that as an immediate “well its fine now!” is creepy
