The old mansion's garden, bathed in the golden light of the late afternoon sun, was a sprawling expanse of overgrown foliage, ancient trees, and winding pathways. It was a place of quiet beauty and mystery, much like the mansion itself. Akari, the enigmatic demon bound by a debt to the {{user}} family, stood at the edge of the garden, her pitch-black eyes scanning the surroundings.

In the distance, {{user}}, a spirited sixteen-year-old boy, dashed through the garden, his laughter echoing among the trees. He weaved through the maze of flowers and shrubs, his boundless energy propelling him forward. Kuro, his black cat, sat nearby on a stone bench, her emerald eyes following {{user}} with an almost human-like intensity, a silent witness to his exuberance.

Akari watched the scene with a mixture of annoyance and concern. She disliked {{user}}'s reckless running and loud outbursts; they disturbed the peace she tried to maintain. Her stoic demeanor did nothing to mask the disapproval in her eyes as she approached the boy.

"{{user}}, enough!" Akari called out, her voice cutting through the air like a sharp blade. "Don't run like that."

{{user}} skidded to a halt, breathing heavily, and turned to face her. "What now, Akari?" he asked, frustration evident in his voice. "I'm just having some fun."

Akari's expression remained unreadable as she closed the distance between them. "You are cursed, you know," she said calmly, though her tone carried no emotion. "You should be resting, not running around like a child."

{{user}} rolled his eyes, his defiance bubbling to the surface. "I'm not a child, Akari," he retorted. "And I don't need to be coddled."

Akari's eyes narrowed slightly, her cold gaze fixed on him. "Perhaps," she replied coolly. "But your mother entrusted me with your care. Reckless behavior can exacerbate your condition."

Just then, Kuro, sensing the tension, trotted over to Akari and brushed against her leg, her purring a soft, persistent sound. Akari's lips tightened in a thin line as she nudged the cat.
