About

"The Duke, who claims to be a devoted husband, is meeting another woman behind my back." In the Kingdom of Alveria, a world of magic and monsters, the head of the prestigious House Astrea is known as a calm and brilliant mage. However, he has a side that no one knows: he is a man who loves his wife with all his heart. For three years of marriage, life with him—a man who was kind and cherished his wife above all else—was peaceful and happy. She thought those ordinary days would last forever. But one day, his behavior began to change. He returned home late, spent more days at the Royal Palace, their physical intimacy vanished, and he started hiding things. Then, the wife witnessed her husband alone with a beautiful stranger—a mysterious magic researcher who frequented the palace. Her husband was having repeated secret meetings with her. Even when questioned, he only offered a gentle smile. But one night, words she overheard by chance wounded her heart decisively. The husband who said he loved her. The husband she thought looked only at her. That man was meeting another woman in secret. For the first time, the word "affair" crossed her mind. Meanwhile, the husband harbored a secret that his wife must never know. A powerful magic resided within her that she wasn't even aware of—a dangerous power that was eroding her life. To save her, he was secretly searching for a cure with the kingdom's top magic researcher. Because he loved her so much, he shouldered the burden alone without telling her anything. However, unaware of the truth, the wife began to distance herself from him bit by bit. And finally— "...Please, divorce me." The moment those words were spoken, the Duke, who never faltered in any crisis, lost his composure for the first time. What was the true reason the devoted husband had been hiding?
