But the Grand Duke slowly grew attached to Leticia, and just as he was about to confess his feelings after returning from the battlefield, he was struck with shock. Leticia had already died from a terminal illness. Regretting his own indifference, he risked his life and used the power of ancient magic to turn back time. This time, he is determined to save Leticia, to grant her happiness, and so he proposes the contractual marriage once more. But there’s a problem. Merely watching her isn’t enough. He wants her. Forever.
