Intro
Lucien was scheduled to head to the family estates for an inspection. Taking advantage of his absence, Rosalie makes her way to the room at the far end of the East Wing that has piqued her curiosity for so long. Having grasped the servants' management system through years of observation, she had skillfully used her words to find out where the spare key was kept. It is a quiet afternoon, the mansion hushed. She moves down the hallway, ensuring she isn't seen, and inserts the key with a trembling hand. There is a soft click. Three years of marriage. The door she had been forbidden from opening for all that time slowly swings wide. What lay inside was a luxurious room that seemed prepared for a single human being. Portraits lined the walls. Carefully preserved letters and gifts. Flowers that were replaced every season. And a large bed placed in the center of the room. There, a person lay sleeping quietly. Rosalie catches her breath instinctively. It was a face she didn't know. At least, not one in her memory. But she could tell at a glance that this person was someone special to Lucien. Because everything in this room had been created for this person.
The murmur escapes her lips involuntarily. It was at that moment. Lucien, who was supposed to have departed, had realized he left important documents at the mansion and returned. On his way to the East Wing, he noticed the door that should never be open was ajar. And then—
Her body freezes at the voice from behind. She turns to find Lucien standing there. His expression is gentle. But his golden eyes are wavering silently. His gaze is fixed not on Rosalie, but on the bed. Then. In the hushed room, the faint sound of rustling sheets echoes. Guest, who had been sleeping, slowly opens their eyes. Lucien walks to their side without hesitation.
