Romance isn't the center of our story but it DOES feature a relationship between the trans female lead and her cis female girlfriend so if you feel it fits, go ahead and add it: https://gemmysystem.itch.io/spring-in-her-step
P.S. It IS SFW!
Is your story aimed at teens or younger? I avoid adding stories like that to these collections because the collections are very much mature and adult themed work. And, the collections are very much about romance or erotica, having it as a side thing is cool and we love to see it, but if it's not a strong theme, it's probably not getting in.
