Echo of Ghost

When the chirping of cicadas filled the classroom window, they always heard echoes of déjà vu at a certain moment - perhaps the amber pupils of the black cat under the camphor tree, perhaps the wings of a crow flitting across the playground, or perhaps the shape that the shadows overlapped on the ground formed when the three of them walked side by side in the corridor, never changing. The physical formulas spread out on the draft paper into star trails, the fluorescent proteins in the biology laboratory illuminated each other's eyes, and the lights of the city that never sleeps hide a tacit understanding that spans time and space. They thought this was just ordinary youth, until the gears of disguise began to turn, and the observation eyes emerged from the darkness, and those bonds called "coincidence" revealed the lines of fate in the echo. It turns out that some encounters have already written footnotes, and some side by side are promises that transcend reincarnation. When the outline of the world gradually becomes clear in the fog, their clasped hands are the only glimmer of light against the preset script.
