First time i ended up going the Axel route which does unlock hot scenes between you and Axel. (Made my day!) But i also wanted to go the neutral route because i didn't want the bad ending with Nauxus. Taking this route is sweet with Nauxus but then you dont get anything with Axel which disappointed me as i prefer Axel. I have both routes saved, but hoping the developers put something in going forward so you can also go out with Axel like with Nauxus.
