Ming Rushi grew up in a household with an average income. Though her father was the heir to a publishing company, it was in the brink of extinction when it was passed on to him. He managed to keep it afloat for some time before they decided to sell it and venture into the jewelry industry.
She had an elder brother who will inherit the company, so she decided to start her career in ZFC branch in City B.
Her final goal, in reality, was to take whatever belongs to Midor Xiu. She never liked Dan romantically, maybe a little interested when she first saw him, but that was it. She just targeted him when she found out that he was close with Midori.
Since the goal of breaking them up was accomplished, she just continued to work in ZFC until her transfer was rejected. Thus, her next target came early as she transferred to XCG.
