After a hundred tolerances, I abandon the empress — Episode 3

Graham Whitmore, the white-robed chancellor, owed everything to the late emperor, so he gave everything back. He aged prematurely, wore white for the kingdom, and made a deathbed promise: he would tolerate the new empress one hundred times. Whatever the cost. It didn't matter how many corrupt ministers she backed or how lost she became. One hundred times, he would bow. But when the hundredth time arrived? Graham would leave, never to return.
