i'm completely fine with OP MC's wanting to live a nice calm life but god damn you're pathetic MC. the king kidnapped you and tried to murder you, you let him live, you let his corrupt nobles and army live, you left your fellow isekai compatriots behind so now they're stuck as slaves to the king and now the king not only took credit for your actions but also made you the most wanted man in the kingdom...
what is it with japanese people and being such submissive pushovers in isekais?
