I think the content of the IOU is that she will receive money when the father dies? Then MC was killed so that the step mom will get the money instead. Pretty rare contract. Usually they will just sell out a female family member but i guess even a monster like aster cares for his sister. Half assed tho. But anyways W father.








AIN'T NO WAY?? THE MOTHER LEGIT DIED???
I hope there is still a twist. Would be kinda disappointing and dumb to let her die to some random bandits for no reason.
