no, that relationship would be very destructive.
roxas couldn’t have had feelings for axel, not romantic ones. he always gave off this sort of – cautious air around axel? and maybe some people will disagree, but. i think that even if roxas was really open with him, he tended to be really guarded. if there was something that was important to him and axel questioned it at all, he got angry with him for it. i think that in a way, roxas kind of felt like axel wasn’t necessarily a person to be trusted? even if he didn’t understand what these feelings meant, i think he had them.
but, he has a really warped understanding of feelings and he wasn’t developing in an environment that was suitable for him (roxas also wasn’t really the type to question axel either, since he also had this notion that whatever axel said was what he should understand since axel remembered what it was like to have a heart), i don’t think roxas could explain why he was so condensed around axel. if you were to ask him, he honestly would probably have no idea what you’re talking about.
roxas is this way with just about anything. when he wants to know something and he receives an answer, be it half-assed or otherwise, he seems to think that this answer is all he really needs and fails to question beyond that (depending on who you are; looping back to what i said, he tends to just go with the word of his fellow org. members since they know what it was like to have a heart, therefore roxas believes they are legitimate sources). perhaps this restraint is admirable, but from his standpoint, it only made things more annoying.
over time, he grew increasingly irritated and frustrated with axel to the point where roxas blew up in his face and didn’t speak to him again (disregarding their encounters in kh2, because roxas had no memory of axel during that time frame). roxas and axel were always constricted, but it was more subtle at the beginning of the relationship. when roxas finally got the idea he should seek answers, axel only continued to push his buttons until he couldn’t take it anymore.
roxas having feelings for someone who was manipulative and someone who wouldn’t give him what he really needed is unlikely. he’s pretty straightforward when it comes to his emotions and he’s pretty narrowed. having feelings for axel would probably just piss him off even more because now there’s something else he can’t explain, and you and i both know axel won’t give him a direct explanation for it.
