She is not a born bad person, but a person who is extremely lacking in love, has incomplete cognition, has no self, and is always grasping at straws:
At the age of 19, she regarded the sweet words of a married man as the whole world, and gambled on a false relationship of being "preferred" at the expense of dropping out of school, breaking up, and losing her body;
She thought that the stolen marriage was her destination, but she didn't understand that what she gained through betrayal would eventually be betrayed by others;
After her husband cheated on her, she had no ability to save herself, so she could only use gambling to numb the pain, draining her family's love into debt and forcing herself to the point of no return;
The hasty choice of a second marriage was the last "gamble" in her life - betting that someone could pull her out of the quagmire, but she lost her last hope.
Her absurdity is the combination of ignorant bravery, paranoid stupidity, and desperate struggle. Every step is terribly wrong, but every step reveals involuntary sorrow.
