Can someone give me some spoiler

#1

I’ve only read until C140. I really like MC strong personality but ML was such an a**hole it’s annoying the hell outta me. He even left her to (nearly) die in the prison but so far he never apologize for what he did back then. When MC began to treat him coldly, he only take it as cute child throwing tantrum. Obviously he has no guilty conscience.
Can someone tell me: will he ever apologize for what he did, especially about leaving her dying in the prison? Will he ever change?
