I'll point out - the trainer won't be a main character in the story, in case anyone is wondering who he is. He will have a role in the story though...
The character plays a small role to move the plot, and offers potential interracial if I have the bandwidth. I’ve always said I “hope” to add certain tags like interracial. This won’t be Anna going to the gym to work out with him. She already has a gym and she for sure doesn’t want to go where David and Alexia go. If there’s eventually interracial, it can be avoidable.

Read it first, and then write! That’s what my teacher told me!
