Slavery is as planned,.. The other worlder set it up for the sake of our beloved mc so he would be safe in any harm coz he find him to be kind and honest guy..
Read between the text they did not trivialize slavery with just the simple debt.
Uh there was no need for either of them to become a slave. Furthermore the MC kept rejecting the offer of her being a slave and she was insistent on being a slave as if it was something great also those two girls did not break the potions so if you were talking about compensation then one of those guys that actually broke the potions can pay for it or work it off or a part of their pay could go towards paying it off no one needs to become a slave and they kept throwing around the whole slave slaves slaves I'll become a slave oh I'll become a slave
One the female characters are annoying AF and two they trivialize slavery as if it's as if it's nothing and I know it's a manga or whatever but I feel like there's just some things you don't just play around as if it's nothing
