"How can we help him get back to his old self, and fix his reputation?"
"Maybe explain what really happened to everyone?"
"But then that would hurt OUR reputations! I know, let's try to fix the guy with trust issues and a strong dislike of romance because of us up with the girl we know nothing about!"
Seriously, the only one of the girls I can KIND OF sympathize with is the former bookworm. She didn't accuse him and actually thought he did something. All she knew was that there was an earthquake, he was on top of her, and then everyone was yelling that he was assaulting her. The friend that took years (Maybe) to say "Hey, you know the nice kid that you talked with in the library a lot? The one that's a social outcast (Again) because people saw him on top of you during an earthquake and assumed things? I never told anyone, but he didn't assault you, he protected you!" is a problem though. And as soon as she found that out she went and tried to connect with him, but stopped short of actually trying to do... ANYTHING to help him. Still a terrible person, but she at least had a REASON to distance herself from him unlike the other 2 who were just too cowardly to instantly fix a problem, or trying to LITERALLY MANIPULATE HIM INTO BEING DEPENDANT ON HER.
