I read the introduction to the game and some things don't make sense, parents who divorce and don't want their daughter leaving her with her grandmother is something that can be there, but why after the death of the grandmother she is not entrusted to one of the parents? Did something happen to them? Usually an attempt is made to entrust the child to a close relative, so in this case the tag on incest lapses as there is no blood relationship with the adoptive family. Because to talk about incest you need to have a blood relationship between two people.
