Mon Rak Asoon

Terd is a rich widow, who became an alcoholic after the death of his wife Da. He lives with his son Num, a troubled kid that has no parent guidance. When the two moved to the country to live in the farmhouse, his son Num decided that he didn’t want to go to school. Terd then hired Nampueng to home school his son. Although Nampueng didn’t like Terd, she took the job because she needs the money to pay off her parent’s debt and for his medication. Nampueng needed the money in advance so he gave it to her in one condition, that she has to live at their house, educate his son, be the housemaid, and work for one year.
