just the nanny. obviously luna doesn’t want to become head of the clan so she doesn’t have a motive, and their mom is unbiased. meanwhile at the time the nanny created the assassins and cursed the mc everyone thought that luna would become the head of the clan and the nanny likely saw mc as a threat because he chose the sword of the founding patriarch when he was a baby
Yeah, I agree, it's the only the nanny, in my opinion her future plan is either to kill all the other candidates to become patriarch so that Luna has to become the patriarch or that she has chosen a replacement for Luna and she is trying to suport that person so that she can control him or her in the future. In my opinion it's probably the second one...
Luna is gonna be so sad when she finds out the reason he was so distrustful of family was her nanny and that her own nanny, someone she trusted tryed to kill her dear brother not only once, but twice now...
If its the nanny, then does that mean it's the mother? The oldest sister? Or just the nanny who is loyal to the oldest sister?
