Tang Tang’s father went another step with a woman whose son was a few years younger than her. In Tang Tang’s heart, there is no mother and brother. Because her father is a successful businessman, and her stepmother is a bartender. Tang Tang has always been more condescending and superior to them, because she believes that they are a parasite of her father and son. One day, she loudly insulted her stepmother as a “slut”. This was known to the son and he planned to dishonor his mother.
