This short story is a period of time taken from a few ordinary people. During this period of time, some very ordinary things happened to them and each other. The story itself is like a drop of rain in a heavy rain, a grain of sand in a desert. If I hadn't written it down, even I would have forgotten it in a few years, and then it would completely disappear from this world, leaving not even a shadow. Now, I have written it down, which can be regarded as leaving a shadow.
Intention: recall youth and record youth.
