Any stories where it's the main good guy x main girl x main bad guy (though doesn't have to be main, just a bad guy.)

Can be action/adventure/mecha/etc. Just there's a good side and bad side. Maybe the girl doesn't realize he's bad or maybe she does. In the end, she ends up with the main good guy though.

Also if there's any where she's with the main bad guy at first like she's evil as well, but becomes good and ends up with the main good guy, that would be neat to see.
