She is very beautiful, but she is also mentally unbalanced. Then the father dies, leaving Fak to care for his insane stepmother. Soon Fak's neighbors in this remote village are talking about him, saying he is sleeping with his stepmother. This rejection by the villagers sends Fak into a spiral of despair.
