The Jing family didn't know much about Shi Jiu's past. Even Jing Shimo knew very little about it. But Yun Ni had been with Shi Jiu for many years and knew a lot of secrets.
For example, Shi Jiu, who no one knew, was the God K.
As well as the old and recent grudges between the God K and the large arms families, and other secrets, Yun Ni knew, but she was unable to find out the sexual orientation of Shi Jiu.
When Shi Jiu first came to the South East continent, Yun Ni had a crush on her at the first sight. Then she realizes how bad Shi Jiu's character was after they had a deep contact!
At that time, Yun Ni came to Shi Jiu's side in disguise to teach her how to behave like a human. However, it was a bad thing for her to make things happen in a casino.
Then, Shi Jiu used more than ten ways to kick Yun Ni's ass to taught not to be too arrogant when she was out. However, Yun Ni was born arrogant. How could she submit to Shi Jiu's punishment at once?
