Alright, yeah, this is a pretty common misconception so I'll be blunt. Hope I don't seem rude.Komaeda's feelings for Hinata have absolutely nothing to do with hope or hope's peak academy.
It's easy to see how one would get that impression, but it's made explicitly clear in the drama CD
that basically spells out their relationship that the reason Komaeda cares about Hinata (whether you want to interpret it as platonic or romantic) is because Hinata kept talking to him and trying to understand him after chapter 1. There's also the scene in the hospital
in chapter 3 when Komaeda has the liar disease, and this line after
the chapter 4 reveal. His actions in chapters 4 and 5 are complicated as all hell an would warrant an essay of their own, but the bottom line is that it's not that he didn't care about Hinata, but he's basically the Unfettered trope incarnate and is willing to throw everything
away in pursuit of hope and even then he arguably left the chapter 5 case open for the students to solve
Then there are his Dangan Island events
, where he obviously cares about Hinata and says he can enjoy even the silence with him, and the ending
where becoming friends with Hinata is the good luck that made everything worth it. Dangan island isn't canon, but the characterization is. Same characters, different situation.
My own interpretation of his feelings towards Hinata is that Hinata was the first person he ever felt similar to, since everyone always shut him out for one reason or another, and he tried to frame the feelings he developed in the context of hope he uses as a crutch to keep himself from falling to despair (hence why all the suggestions he makes re: Hinata's talent in his first FTE are jokes save for soothing presence/comforter) so he wouldn't have to properly face the fact that he cares about someone, keeping in mind that everyone who's ever been close to him has either abandoned him or died. When Hinata doesn't completely brush him off like everyone in his life has and still tried to understand him, even under the pretense of fear (which he drops in Komaeda's fifth event), it's enough to make him fall in love with him, but he's still afraid of facing his true feelings and thus pushes him away when they're about to reconcile, and definitely isn't willing to prioritize Hinata over the belief system that's been keeping him going. Yours may vary, but I do hope that makes sense.
So... all that said, I don't really think it's right to say Komaeda doesn't care about Hinata as a person at all. His priorities are extremely skewed and he's not entirely sane, but that doesn't mean he's incapable of having actual feelings for another person.
Also... I just want to make sure, but have you read his freetime events
? Because the last one comes with what's pretty clearly an aborted love confession (read the TL notes).
