The article tells from the perspective of a son. While the mother is performing her lewd and coquettishly in her lover, she is dignified and kind in front of her son. In the end, she is threatened by the evil person and loses her identity as a mother in front of her son. She is completely unaware that her lust has been seen by her son. Perhaps this is the difficulty of a mother and a woman. She has to work hard for the family and cannot bear to give up the physical joy she deserves as a woman. It is really contradictory and wonderful!
