I've started "This Isekai Maid is Forming a Union!" which is about stopping:
Otome protagonists abusing their power, slapping maids, and using them as pawns to do their dirty work.
Given that the only Otome Isekai I'm familiar with is Tearmoon Empire, if that even counts, I'm very unprepared to read this, nor do I want to read about such physical abuse, so I'd like some foundational history?
What's the first "Otome Isekai" to feature the protagonist slapping a maid?
