@Juggernautbob seems like someone is forcing you to read the title you don't like, though it's clear from the description alone that the story includes slavery in it, poor you. Well, I can understand you in some way, for example I don't like NTR, BL, shoujo/josei, shota/loli, and there is a crap load of stuff like this here, but I don't go everywhere and try to ruin everyone's mood just because there is something I don't like, or think is bad and wrong.
Slavery existed for millennias and is a common part of medieval-like settings, deal with it. It is one of the ways to deal with people who committed crimes or have huge debts without making other people pay instead, like we have in modern societies (jails, bancruptsy programs, etc.). And if the boundaries of what you can and le. Color me surprised.
