I Woke Up Married to a Ruthless Lord

Jiang Wanyin marries Fu Zheng, the Marquis of Jing'an, and on the wedding night he comes at her with a sword. She is not the woman he thinks he married. She was an office worker who died of overwork and woke in this body. She uses what she knows from that life. She audits the household accounts, finds the money going missing, reorganises the staff, and needles Fu Zheng while she does it. What she does not know is that he can hear her thoughts. He is cold in public and devoted to her in private. Together they go after Shen Qingyuan. Fu Zheng is imprisoned, and she risks her life to get him out. Then the system that brought her here sends her back to the present day, and Fu Zheng turns up in her world in a suit.
