She thought she was married to love.
On the wedding day, Shen Zhiyi saw with her own eyes the private conversation between her husband Lu Ziming and her father-in-law Lu Jianping - her marriage was just a conspiracy that had been planned for three years.
Her father-in-law was the murderer of her father, and her husband only married her so that she could sign a document giving up the inheritance.
The inheritance trust left by her father was locked, and she was only one key away from the huge wealth.
But she didn't collapse.
When her father-in-law thought she was in the bag, when her husband thought everything was under control - she started to fight back.
An account hidden in the basement of an old house records the secrets of this wealthy family for thirty years.
A husband who pays money on time every month but never shows up, a father-in-law who is more complicated than imagined, a truth that gradually emerges...
She wants to take back everything that belongs to her.
Not to be an abandoned wife of a wealthy family, but to let everyone know that everything owed to her must be paid back with interest.
