Heartbreaking but disappointing ending*****spoilers***** all the men in MC life have either betrayed or failed herHer father "sells" her to sociopath Keisuke to save himself without reading the small print. Naively assuming keisuke will marry his daughter.Even when told that she will be used as a sex slave loaned to powerful menHer father still yields to save his own skin.Yet the mc is never angry at her dadHe is worse than keisuke, to do thatReiji - supposed love interest.despite knowing what is happening is wrong. Does nothing. as Luna is frequently traumatised by the "guests"Keisuke - depraved& no redeemable traits. tortutes & humiliated the MC reducing her to a communial sex slave for profit.The actions he commits is vile& criminal and he never gets punished for it.the ending1) the mc is never angry at her father who betrayed her& abandoned her knowing she would become a sex slave2) keisuke never gets punished either for what he did to Luna3) she ends up w/reiji
