The prosperity of the fleeting years is fleeting, life and death are the helplessness of life, what is left is that things have changed, but the lover is still the same, indifferent, stubborn, pretending to be strong, who comforts with gentleness, who treats each other with true love, who wipes away the pain, and then there is another joy and sorrow. Not every story needs to start and change, but often everything changes in a turning point.
