"The bully was one of his real friends all along" trope, that's rare, I mean compared to the other malicious people who scheme to cause MC pain behind his back, being upfront with your hostility is definitely more noble and the lesser evil, but yeah for now he's just a shithead, maybe he can develop to be MC's best bro, I actually wouldn't mind that development, bro's character design practically screams MC's sidekick haha.
