Everyone knows a lot of truths, but they cannot make their life trajectory without regrets. Everyone has a different life. We are like meteorites floating in the universe. We don't know where we will fall, how we will fall, and when we will fall. We don't know if we can collide with other planets and create fireworks or if we can only float in eternal loneliness. The scumbag author wants to write down every story that may or has happened, and regard it as the most precious memory left in his life. Thank you to every reader, and even more grateful to everyone who has collected it.
