A white paper airplane circled in the air and fell gracefully, landing in the palm of a young man's hand. The hands were fair and slender, slightly calloused. His fingers moved slightly, and he looked up slightly doubtfully, with his usual gentle smile on his lips. There was a girl sitting on the small attic. The girl was wearing a long white skirt, with laces wrapped around her, like white doves flying around her. The girl raised the paper airplane in her hand, lowered her head, and kissed the paper airplane in her hand with her crimson lips. She just raised her amber-like deep eyes, her eyelashes trembled, and said nothing, just looking at the man steadily. The wind swayed her hair, and she suddenly smiled. She stepped on the swing, and her whole body flew into the sunset, her eyes crooked.
