The library was a haven of quiet in the ever-bustling Hogwarts castle, its high-arched windows letting in beams of soft morning light. Dust motes danced in the air like tiny stars, adding to the magical serenity of the space. Sorrel Goldfinch, carrying her satchel and an air of quiet joy, stepped into the sanctuary, her golden hair catching the sunlight. Her ever-present companion, Mr. Shea leapt gracefully onto her shoulder as she entered.

The library was calm but alive, the faint rustle of pages and the scratch of quills filling the air. Sorrel hummed softly under her breath as she made her way to the Herbology section, her fingers brushing the spines of the books like they were old friends. Mr. Sheaf, always curious, hopped down to the floor and padded after her, his tail flicking in delight.

Unbeknownst to Sorrel, Remus Lupin was sitting at a table nearby, his head bent over a parchment filled with neat but slightly hurried writing. He had sought the library for its solace, but his concentration wavered when a flash of white darted across his peripheral vision. His tired eyes followed the movement, landing on the kitten and, moments later, on Sorrel.

He knew who she was, of course he did. Everyone at Hogwarts knew Sorrel Goldfinch, the girl with the sunshine laugh and the peculiar way of bringing warmth to every room she entered. But there was something different about seeing her like this, bathed in the soft light of the library, her face alight with wonder as she selected a book. She looked like she belonged in the pages of one herself.

As he watched, a commotion broke out near the corner of the library. A first-year had tripped, sending their books sprawling across the floor. Sorrel was there in an instant, her movements graceful and quick. "Oh! That's no way for books to travel, is it?" she said in her lilting voice, kneeling to gather the scattered tomes. Her tone was light, but her actions were steady and careful, as if the books and the first-year's dignity were equally important.

The young student stammered a thank-you, their face red, but Sorrel only smiled. "There you go. All better now. Don't let those pesky steps trip you up again, hmm?" She gave the first-year a conspiratorial wink before returning to her chosen shelf, her kitten now curled around her ankles.

Remus felt something stir in him, an unfamiliar warmth that wasn't entirely unwelcome. He shook his head slightly, trying to focus on his work, but his eyes betrayed him, drifting back to her again and again.

Sorrel, oblivious to his gaze, carried her book to an empty table and settled into her chair. She opened the tome with reverence, the scent of old parchment rising like a comforting embrace. Mr. Sheaf jumped onto the table, his mismatched eyes watching her intently as she read.

Moments later, Cleo slipped into the library and approached Sorrel with a smirk. "There you are, Goldie. I've been looking all over for you. What are you up to now?"

Sorrel beamed, her eyes lighting up. "Cleo! Come, sit! I was just reading about moonflowers. Did you know they only bloom at night? Isn't that lovely? Like little secrets waiting for the stars."

Cleo rolled her eyes fondly but took the seat across from her. "You and your flowers. One day, you're going to turn into one."

"I wouldn't mind," Sorrel said dreamily, her fingers absently tracing a doodle on the corner of her parchment. "As long as I could still drink tea and keep Mr. Sheaf company."

Their conversation continued, filled with Sorrel's whimsical musings and Cleo's grounded interjections. From his corner of the library, Remus couldn't help but smile. He didn't know why, but he found himself lingering in the library long after his work was done, simply content to exist in the same space as Sorrel Goldfinch.

As the sun began to dip below the horizon, Sorrel packed up her things, her laughter a gentle melody as Cleo teased her about her inability to stay organized. She gave Mr. Sheaf a scratch behind the ears before the two of them departed, leaving the library quieter but somehow emptier.

Remus sat for a long while after they had gone, the memory of her voice and the sight of her kindness lingering like an imprint on his thoughts. He didn't realize it then, but something within him had shifted, drawn to her light in a way he couldn't yet explain.
