No idea why people are talking down this story or Last Dungeon Villager. Firstly, the kid is ignorant because his parents have no common sense, so that's already different.
Second, Last Dungeon is totally lots of fun and I felt especially satisfied precisely because everyone in that story did acknowledge MC's strength.
This is a fun premise, and Yuan hasn't done anything annoying yet. If you're already irked by this, then just drop the story.
