Notebook Folded in Half

The girl opened the yellowed notebook, and the origami airplane slipped from the pages. The sunlight shines through the window lattice, revealing the green handwriting hidden in the paper marks - it was a love poem written by a young man, which was hastily stuffed into her schoolbag on a rainy afternoon. Nowadays, the parasol trees outside the window are still there, and the people who know the sound of cicadas are just folding paper airplanes, and they have already flown into the sky of another city. She gently put the paper airplane back on the page, and suddenly felt that time could be folded in half, so that the summer of twenty and the rainy day of seventeen could overlap quietly at her fingertips.
