I can see where you are coming from. For me, I don't mind it. I actually imagine the narrator having a same voice as the the English dub of Hetalia's narrator.
Ooooooh, that's good
I think it's because the manga tried to replicate the witty narrator everyone loved in the novel!! It's more awkward in the manga, but you'll probably learn to love it later.
it's cringe af. it would've been fine with the misunderstandings occuring on its own, but it's so awkward reading the narration repeat it's joke over and over beating it to the ground.
