The content is exactly as the title suggests, the author's time diary. He puts all kinds of thoughts into the storage room. If he loses his memory, can he take it out and read it? ? (Laughs) Most of them are essays, and there may be weird things mixed in (such as dark love letters), but the others are really serious (with a straight face). I record time and all kinds of people I interact with. Who knows if you will be a new memory in my storage room...
