In her previous life, because of the engagement, she married into Ji's family. Unexpectedly, Ji's mother died that night. People in the courtyard said she was her nemesis. Not long after, Ji Huainan left on a mission again. Shen Yunxiu couldn't bear the loneliness and being alone with a person. The educated youth who returned to the city ran away, but were sold...
It wasn't until the moment she died that she saw on TV how happy her cousin Shen Yunshu, who was married to Meng Jue, was now as the wife of the richest man.
If he had to do it again, Shen Yunxiu vowed to take away everything from his orphaned cousin. Let’s start with the marriage change first…
