So your telling me that all it took to eradicate slavery from a kingdom full of underground slaves and slavers, was the princess seeing it happening and then getting the advice.... "Try"?
I mean it works, I guess but dang man. Thought there'd at least be some build up, like she was trying and then his advice shook the hearts of the kingdom and that's why she's grateful. But no, the woman literally needed to be TOLD to make an attempt.
Her Yandere side better make me feel like I'd wake up with a chainsaw up my butt if I dated someone like her, that's all I'll say.
