Exalted Favor and Forced Marriage: the Story of the Regent's Rise to Power

She was appointed to serve as regent and supervise the country, and raised her young brother. She squeezes out sycophants, eliminates troubles, is smart and iron-faced, but marriage is a problem. He is the regent, free and unrestrained, but cruel and sinister. He is the most notorious minister in the court. One is a noble person who endures humiliation and bears heavy burdens, while the other is smooth, deep and ruthless. And when they collide, what kind of fireworks will they create? (This is the story of a hero and heroine who join forces but want to chop each other into pieces every minute.)
