Fallen Angel's Waiting

Someone told me that the memory of a fish is only 7 seconds. After 7 seconds, it will not remember the past. Everything becomes new again. Therefore, the fish will never feel bored in that small fish tank. I would rather be a fish, forgetting everything once the 7 seconds pass, the people I have met and the things I have done can disappear. But I'm not a fish. I can't forget the one I love, I can't forget the pain of caring, I can't forget the pain of lovesickness... I don't know how to write an introduction, so feel free to use these instead This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
