Because one day, I saw a girl writing something on her scarf and saying: "How can there be so many unique things in the world?" This sentence woke up the dreamer. In fact, what I want to say is that although life is an RPG, the inherent bug is that there are no save points. Once some things are missed, there is no chance to do it again. So all you can do is hold on to what you want to hold on to the most and don't let go.
