There is a kind of person in this world who stays up day and night. Because during the day, all the darkness will be too dazzling. For example, Shadow's "profession" is that she is the mistress that everyone shouts about.
There is still a kind of person in the world who can be a peaceful lady during the day and be crazy at night, like Lisa.
Although these two kinds of women don't have much in common, and they don't talk much when they get along, everyone in this world is lonely, and they are even more so, so they stick close to each other to keep each other warm when it's cold.
There is nothing in this world that makes people unable to let go. It's just that their hearts have nothing to rely on. Once they have something to rely on, it doesn't matter anymore.
