But she is too agressive for now.
He want her to wait 3 years to be legal (and to give his daughter time, she still didn't recovered), but she don't want to wait, because she want to run away from home (and i can understand that, her mother is creepy and potentially dangerous).
So yeah...It will be a disaster once anyone know the truth.
