Remember the Terminally Ill Grand Duchess

To Grand Duke Heverus, marriage was merely a tool. Thus, his marriage to Letricia, the adopted daughter of a Count, began simply as a one-year contractual union. But the Grand Duke slowly found himself drawn to Letricia. The moment he returned from the battlefield, ready to confess his feelings, He was shattered to discover she had a terminal illness and was already dead. Filled with regret for his indifference, he used an ancient magic, staking his very life to regress. Now, he is determined to save Letricia no matter what, to secure her happiness. He turns back time and proposes their contract marriage once more, But this is trouble. Merely watching over her is no longer enough. He wants to possess her. For eternity.
