Later, Huang Min learned from her stepsister that her father had been after her mother's money from the beginning. When he married his mother, his father was already with Huang Li's mother.
Huang Li and her younger brother were Huang Min's father's children.
Huang Min's father used Huang Min to threaten her mother so that she would transfer the company to him. Then, he gave Huang Min's mother a slow-acting poison until she was admitted to the hospital in a coma and became a mental patient.
It was only then that Huang Min realized that her existence was a joke. She was her father's excuse to threaten her mother.
However, at that time, Huang Min was weak and could not find anyone who could help her. She could only please those people so that they would pay her mother's medical fees on time.
