It actually isn’t like that. Looking at where you stopped it’s later revealed that MC used to compete with his would be bully, but bully is literally insane and he killed his mom and kidnapped his childhood friend just because MC tries to compete with him, so MC is traumatized by that. but I myself haven’t read it in a while so I don’t know what happens after that.I myself stopped reading after ch. 171. I just don't like how mentally weak MC was. And with MC's bully in the original world also being there (real jacked, alpha vibe, with really bad personality to boot) I wasn't surprised MC getting NTR'd.
