the MC's morality is a bit wishy-washi, first they buy a slave just for sexual purposes but then explicitly calls out consent as an important thing, only to then seemingly make an aphrodisiac, something that prevents the use of consent.
you know, Halo-chan should start from become Filial's lover. considering Filial already has so high affection toward Halo. slowly but sure, they will going to point as sexual couple anyway. it's just the matter whether Halo being patient or not......or most likely not, because she bought the succubus essence there. it's clear that she wants to have sex with Filial as soon as possible.....
