Zhong Wei Xing is the third young mistress of the Zhong family. Her elder brother, Zhong Tian Jun II, is set to take over the company from their father. Zhong Ruo Qi, her sister, is also set to take over the position of director of the design team from their mother. Ni Ni is the only sister she can relate to, even if they are not blood, but Ni Ni hasn't been home since she went off to a conference in Milan and Wei Xing is feeling a little out of place. And so, the third young mistress to the Zhong family ran away from home hoping to find her own way in the world... Away from her parents and siblings might and power as the leading jewellers in the world.

E. shine's young mistress is the title.
