Maya skipped through the park, her laughter echoing in the crisp autumn air. The colourful leaves swirling around her feet seemed to dance in time with her buoyant mood. She had the wind at her back, everything felt easy. The small, notebook she held in her hand, the one she’d found in Alex’s car, was what fueled her sense of wellbeing.

He'd been writing a novel about her. It wasn't just a story; it was a love letter. She had spent the night reading it, and it was a revelation. A delicious, heart-stopping revelation. She wanted to hug the world.

She reached the familiar bench by the lake, the place where they had shared their first kiss. She sat down and pulled out the book, re-reading the passage about that very moment. The sun warmed her face, and she felt a sense of contentment she had never known before.
