What do you mean "cute granddaughters"? By looks? Maybe by manga standards. Certainly not by attitudes.
I mean as an “immortal witch” she’d prolly be amused by human antics (tho sucky if they inherit her immortality I guess) since even as her own family they’d be a “blip” to someone who’s lived thousands of years? Tho mc could’ve been sarcastic or just used to them if not trying to convince the grandma to interfere
Tho if not nobles, maybe some authors simply like to add “nuisances” in a plot but it’s not like some edgy series where he’d bitch slap them if he didn’t already kick them out (I wonder if some ppl just subconsciously expect some of these charas to be liked/amusing versus just annoying)
I wondered why he put zero effort into explaining things. But seeing how they are, they probably won't listen anyways. Why bother when he knows the outcome? This is a "let them touch the hot stove" situation.
And by hot stove, we mean his romantically interested hot mayor.
I’d wonder if they’d properly learn their lesson versus “why didn’t you warn us/save us sooner!?” Tho the granny’s the one with magic power even tho he helped take down a bear before
Tho i guess if ppl wanna skip this arc they’ll have to come back like six months later depending on the amount of updates
