Yuck that's disgusting. Why would you keep a random slave just because it happens to be a female. Gross. It is just as if he would do anything as long as it is a hole. I'd much prefer he have a male slave, since at least then, they would know their place. Female slaves are just a nuisance, and the MC is probably gonna treat it as if it were an angel. Just think about it, who in their right minds would keep a random female let alone treat them like family/ lover. But no they have to show our MC be kind to girls, even if she was just a slave forced onto him. Why can these shitty MC not just ignore it? Why not say : "Why am I supposed to keep it? Do I get something out of it?". So unrealistic. He sees this world as a game, and yet he has to help every random hole/ damsel he encounters, and annoyingly enough they absolutely have to fall for him sooner or later.
