Alas, I really don't know how to write an introduction. Let's use the comments given by my friends:
The world is so turbulent that we can't see clearly what's ahead. We can be strong, but we can't escape loneliness.
Sometimes gentleness requires more strength than strength.
Is there a man in this world, no matter you give up on him, no matter you hurt him, or cheat him, and leave him time and time again - he can still catch up with you, hold your hand, and hold you in his arms when you need him most?
Is there a man in this world that you will never forget or leave?
