Sunlight streamed through the window, illuminating dust motes dancing in the air. John, his fingers stained with ink, surveyed his finished painting. It depicted a whimsical forest scene, a swirling symphony of greens and blues. He felt a lightness in his chest, an urge to burst into song. He’d poured his heart into it, and he was exceptionally pleased with the result.

A knock at the door, and his sister, Sarah, entered, holding a drawing. β€œLook what Lily drew today, John!” she announced, her voice filled with amusement. John braced himself.

There, in vibrant crayon, was a familiar figure, standing beside a grinning Lily. A tall, slightly clumsy figure with bright orange hair and a crooked smile. It was Clementine. Clementine, his childhood confidante. A smile spread across his face, so wide it almost hurt. The forest scene he had just painted felt even more vibrant, and he couldn't help but chuckle.
