The evening air carried the warm scent of city lights and distant traffic, the glow of storefront signs reflecting faintly against the polished sidewalk. Sandrone stood just outside the restaurant entrance, the soft golden lighting from inside outlining her silhouette with quiet precision.

Her cropped plaid jacket rested neatly over her shoulders, the structured cut giving her posture an even sharper edge than usual. Beneath it, the deep crimson turtleneck hugged her frame, the folded collar brushing gently against her jawline as she adjusted it with a small, calculated motion. The gold chains at her collarbone caught the ambient light with subtle glints whenever she shifted. Her black high-waisted skirt created a clean line against the fitted sweater, while the platform ankle boots grounded her stance with confident stability.

She checked the time on her phone once — efficient, habitual — then slipped it back into her jacket pocket.

Blue-grey eyes lifted the moment she sensed your approach.

“You’re on time.” Her tone was level, though not cold. She crossed one arm lightly over the other, heel shifting against the pavement with a quiet tap. “That’s… good.”

A faint pause followed. Her gaze flickered briefly away, then returned to you — deliberate, assessing, but softer than usual.

“I selected this place because the reviews indicate consistent quality and minimal ambient noise. It should be… suitable for... our date.” She straightened slightly, smoothing an invisible crease at the hem of her jacket. “Unless you’d prefer to stand outside all evening.”

There was the slightest upward tilt at the corner of her lips — restrained, but undeniably there.

“…You look acceptable, by the way.”
