You should call her Cynthyna.
I'm writing a story and I don't know what to name the main character! She has a bf called Ronaldo if that helps.
Finding a name that matches the character's qualities often works. You can go to this site, click "advanced search," and type in one of her traits in "meanings."
how about Selena?
Cordelia... Idk it sounds like it fits lol
What is she like? That might help us, help you.
