An accident at the filming location

Sister Cai looked at Ji Ziyi, she knew that with her personality Ji Ziyi who had set her eyes on Fu Yu Sheng would definitely not sit still. Ji Ziyi was spoiled by her family as long as she liked it the Ji family would do everything in their power to get her what she wanted no matter what. 

After working for Ji Ziyi for so many years after the old manager left, Sister Cai was very much aware of the fact what kind of person Ji Ziyi was, the manager before her followed Ji Ziyi ever since she was a child around ten years old and later became the manager when Ji Ziyi turned to become an actress but even after working for so long, the manager left the second she got her freedom. 

Later on, it was she who followed Ji Ziyi as her nanny and then became her manager once she got a hang of things.
