The world is unpredictable. What is unpredictable is not only the natural white clouds in the sky and the changing weather, but also the incomprehensible human heart and unpredictable world events. The most unpredictable thing is human beings' own feelings. Because the person you want to love may not necessarily love you, and the person you don't love is still in love with you. You think the person who loves you may be taking revenge on you, and the person you think bullies you is actually protecting you in his own way. Sometimes two people who don't love each other can live a peaceful life, but two people who love each other very much have to love deeply and hate each other deeply. Because I love you so much, I choose to give up on you and not bother you by contacting you. I let myself taste all the loneliness secretly. If I can't give you the happiness you want, then letting go will be my last tenderness to you. As long as you live happily, it will be my greatest gratification.
