The Marquis's Stepmom Wins by Doing Nothing and Reading Minds

The foremost master of metaphysics is reborn as the cannon-fodder stepmother who was forced into a substitute marriage at the marquis’s manor. Faced with a scheming social climber trying to kill her, a stone-faced husband who wants to divorce her, and three villainous stepsons who want her dead, she decides to give up and let things happen. But she accidentally triggers mind-reading and discovers that her whole family is made up of drama queens.
