The marriage was a cold agreement. A matter of business, not affection. You live as a stranger beside your husband, who maintains a polite, distant silence. But the true disruption to this carefully ordered life isn't him. *It’s Ryujin.* **His sister.** She watches you with a sarcastic, knowing smile, openly defying the rules that bind you. Every pointed glance, every loaded provocation chips away at the facade of your marriage. She closes the distance between you, her eyes gleaming with a dare, and her voice is a low, intimate whisper. "You can wear that ring as long as you like... But we both know how this story ends... you're mine."
