Maybe you could avoid it if you manage to be only pretty boy in the show. Or if you have really good chemistry with the canon girlfriend and nobody wants to mess with it. Or the movie could bomb and nobody watches it so nobody writes fanfiction about you, but that sort of defeats the purpose.
You might want to go to law school instead. You can at least be rich that way. And you could get some name recognition. My dad's the DA, so he's in the news a lot. But then you're always at work and your marriage will probably fall apart but you can maybe learn from your mistakes and make it work the second time through like mine did. And don't marry an actress. It never lasts.
