My Wife Is a Villain?

"Although she is a snake-hearted person and does things unscrupulously, I know she is a good wife." Reincarnated in the world of third-rate novels, Ewan found that he was actually a minor son-in-law in the duke's palace, and his wife was a villain who could not survive more than a hundred chapters. When he realized that the death of his entire family was imminent and that even he could not escape, Yoon made a decision that went against his ancestors and resolutely showed his cards to his wife. Since you are already a villain, why not be a swordsman and a silver woman?
