There sure is! These are the ones that I found. 

The Soul I Was Never Granted by Ornavy: 

“You have ten lives,” he said as Yuuri and Victoria embraced each other in comfort. “Fall in love in at least one of them.”Yuuri’s eyes couldn’t leave Victoria’s. Victoria’s eyes couldn’t leave Yuuri’s.“We’ll be fine,” Victoria hushed. “I’ll find you. I promise. I promise.”“Me too. I promise. I promise. I’ll find you.”“Ten lives as humans,” the councilman spoke over them. “If you fail to fall in love, you’ll be banished millions of worlds of darkness away from each other.”

This fic is mainly focused on how Yuuri and Victor had ten lives in which they would have to find each other and fall in love in one. And in one of their lives, Victor is trans so it’s really interesting when you get to that part. Though it isn’t necessarily focused on him being trans, he is trans at one point, and this is actually a good story!  

Haven’t You Noticed That I’m A Star by Soulsong26: 

Yuuri was never sure of himself, but became inspired when their beloved celebrity came out as Transgender. Sadly coming out is far more complicated and exalting than it seems.
