So, I'm Scrivere this story and there are these two guys named Brian and Ethan. Ethan is a player but really has fallen in Amore with my main character, Savanna. Brian relates più to Savanna and he really likes her. Who should I have her end up with?

If it's più for wraping up a story, then probably Brian. He seems like somebody who would care for her. But, beware of it becoming a stereotypical ending.
If you're just trying to find a good plot twist o something like that, then I think te should maybe bring the mortal back in somehow. Bring him in, and then te can have her feelings spark back up, adding in to the story, then just two guys fighting over a girl, and whatever plot te already have.
Whatever te choose to do, I know your story will be really good. Hope this helps!:)

Maybe Brian if he relates più to Savanna.

I like hard Amore stories so I would choose Ethan. They could have great adventures.
But if Ethan loves her and Brian only likes her... It sounds like some kind of sad ending. I don't know. My once friend wrote amazing story where someone like Ethan was girl's soulmate but she ended with another one who she could lean on but she never really loved. Idea of Brian&Savanna reminded me of that story but still I would end up her with Ethan o noone ;)

If i were Scrivere this, she would end up with Eathan, idk why..... i justlike stories like that :3

Here is what I would do. Since Ethan is a player...make her end up with Brian first...then towards the end, let her end up with Ethan. Of course he's going to have to gain her trust and work for her but that's the beauty of it. Turning a player into a one girl kind of guy. Let her fall for Ethan, but go with Brian for an easy way out. She knows she's not going to get hurt. Let Ethan struggle a bit with his feelings and let her push her away so there is that much più build up to when they finally do get together. That's my opinion :)

Another guy!! unexpected twist :P

Brian because Ethan is a player, and dosen't deserve her. Hope this helps :D
