Well, by the time he realized he didn't want to be a hero he was already strong enough to earn an easy living with low to mid level adventurer requests easily...he starts going on DEADLY MISSIONS? Why not opening a business or something NORMAL.
MC prob didn't think things through or is a tradition that the hero can become king at least through marriage. It's also not SUPER unheard of for a hero to marry into royaltyhow did he think he could become king while being an adventurer?
This one makes sense though. The 3rd son is acting like a child, so he's being treated like a child. It's also a bad idea to give treats to the entire escort party except one. It can also be seens as thoroughly proving that D ranks are not the kind of trash who discriminate based on another's background.Why is this dude being nice to that asshat after all of that disrespect prior to the trip?
I'll never be able understand people who are that easily forgiving
