She's cartoonishly dumb and her grandfather let's her do anything, the moment the protagonist directly tell her that he hates her guts she'll understand and devolve into a pud of tears and he'll eventually forgive her: she's on the cover for God's sake, she's getting forgiven 100%.
Yeah, you can fantasize about your kink but acting on it is a whole diferent story lol
Though I wouldn't do even what the protagonist does currently, I'm not particularly a horny person towards others and my mind would punish me if I did it.
So, this author is telling me that no one in the world ever had used their MP to 0 until that very moment, so much that none of them knew what would happen?
The girl is a sage, has she never exausted her MP while training before? I feel like that would be rather common.
