After reading all these comments I thought the MC would be pure evil but he's just kinda insensitive and genuinely dimwitted.
Are people really getting mad and totally believing everything narrated by a delinquent who already hates the MC? He didn't even go to the same middle school as the MC and just spreading a rumour he heard from someone else. And even if it's true what he did would be a bit hurtful but that doesn't make him more of a bad person than any other 15 year old teenager with friend group drama. He liked manga for a while so he talked with someone who liked it too, it's not like he bullied anyone or badmouthed him after that.
He kept in contact with his two highschool friends in the next decade so he probably considered them as his true friends and just thought he was just casually being friendly with people like that manga dude.
They keep saying he uses them like tools, but what does he even do except hang out with them and later not talking with them. He's not a bully, a cheater or a creep to girls. His biggest crime is being spoiled and being an idiot who just says anything honestly.
