Doormat? She's the Dominator!

Jian Yimei runs the Rose Group, a finance house valued in the trillions. Years earlier the Meng family paid for her mother's treatment when her mother was seriously ill, and to settle that debt Jian Yimei agreed to marry Meng Que and stay three years. She kept her name and her position hidden and took a job in the family's company as an assistant. From that desk she kept the Meng business running, moving money and closing problems without anyone knowing where the help came from. The family treated her as someone living off them. For three years they insulted her and pushed her around, and she said nothing, because the three years were the terms she had agreed to. When the term is up she leaves. The Mengs are left without the protection they never knew they had.
