Magic Book Ruins My Divorce Plan

After three years in a marriage of convenience, Ethan still isn't allowed to touch his wife, and her family treats him like a dog. Then a magic book awakens in his head with an offer: divorce her, and his grandfather will come back to life—and Ethan will inherit a fortune. So he goes all out to get kicked out, kissing his wife, beating up his mother-in-law, and tearing up their contract. But every attempt backfires, and the worse he behaves, the more his family loves him. Ethan is at his wits' end: "I just want a divorce!"
