In her previous life, her own family schemed against her and her husband betrayed her. In the end, she was branded a "madwoman" and sent to a psychiatric hospital, where she was locked away for twenty years.
When she opened her eyes again, she was back in 1990.
This time, she would no longer put up with it.
Because she discovered she could see IOUs above everyone's heads.
[The Zhou family: You owe me half a lifetime.]
[My birth family: You owe me a life.]
[My best friend: You owe me a future.]
If you owe her, you have to pay up.
In this life, she pretends to be crazy while collecting debts, makes money while uncovering the truth behind her confinement in the psychiatric hospital.
Treasury bonds, subscription certificates, the stock market...
In 1990, opportunities were everywhere, and so were debts.
Everyone who owed her in her previous life would pay it all back this time, with interest. Not a single debt would be forgiven.
