Create a poignant and emotional scene depicting one-sided love

Create a poignant and emotional scene depicting one-sided love. In the foreground, show a person standing alone on a quiet street or in a serene park, looking longingly at another person who is walking away or standing at a distance, unaware of their gaze. The person in the foreground should have a soft, wistful expression, perhaps holding a small token like a letter or a flower, symbolizing their unspoken feelings. The background can include a soft, muted color palette with gentle, fading light, suggesting the melancholy and bittersweet nature of unrequited love.
