The story of the Milk Ogre curse is still accepted in some Burmese villages. The women living in that kind of village misbelieve that if a woman has a curse of milk ogre upon her, her baby will die by taking her breast milk. So, to avoid this tragedy, she denies to breastfeed her baby and rather sells the baby to someone else for adoption and then break the curse. The film was directed for the purpose of expressing this strange obsession.
