The husband moved into the house while the wife's sister moved out saying there wouldn't be room for heranymore. Later on they had children and the husband was liked with everyone in the neighborhood
The husband started having odd behavior like acting differently, leaving at midnight, and having strange smells
The youngest child began to be afraid of the husband, her father, and so did the wife, she tried to calm her down down but it wouldn't work. The husband seemed to have almost no reaction to it.
The husband went outside and the wife was watching him, he started to transform, into a human. The wife didn't want to believe it.
She knew he would kill the children if it had the opportunity, the mother anger came out, she howled and the others heard and came, the sister was also on her way. He tried to fight, or at least tried to be brave.
He ran to a field and the others chased him. Once they caught up to him the sister went for the throat and he died. When the wife got there he was already dead.
