Model response

Dawn leaked over the weathered red-tiled roofs of Willow's End, casting pale golden light on the quiet small sleeping street.
A figure in a black trench coat stepped from an old beat-up sedan, pausing to adjust a frayed leather hat.
His gaze fell on the shattered window of Mrs. Hargrove's cottage, a faint jasmine smell lifting from the broken glass.
Mabel, the town baker, leaned from her porch, her hands trembling as she stared at the morning scene with worried eyes.
A soft creak echoed from inside the cottage, and a single curtain fluttered slightly within the darkened room.
