Every time I read this I get angry. The MC goes and insults a noble without thinking there might be repercussions. I mean you're suppose to be intelligent. Shouldn't you think things through before you start a fight? Perhaps question your father on the exact position between him and his acquaintance? Nope, lets just jump in with "fat pig" and see how things pan out.
Then he immediately backs down to the threat of Dovil. COME ON! If you are going to have a spine, don't lose it immediately. He threatens you with Dovil, you threaten him back with the Prince. The Prince is your friend and a higher power, nope lets just flop around like a goldfish because I didn't plan anything out in the first place. But lucky for him he has MC powers and gets bailed out by the girl he constantly says "I don't like", but according to novel readers he really loves even though it isn't conveyed in the manga at all.
Hell there's probably a ton of crap in this chapter that was skipped over since it sure as hell doesn't make sense that you wouldn't be able to formulate some sort of plan during the time period between when the pig leaves to get Dovil and the time it takes for him to return. It's not like they have cars in that era. Travel back and forth between territories takes time and they aren't next door neighbors. Nope, this story immediately jumps to Dovil being there like it's the same day and no planning or attitude adjustment occurs during the intervening period.
"Why don't you just drop it" I'm sure most of you reading this are thinking. Mostly because I want to see if it actually gets better. So many of the novel readers seem to be okay with the inconsistent writing of the manga that there has to be something else holding it up or at least a destination that isn't as bad as the origin. At least it isn't complete shit like Butsuri-san.
