When you grow old, you will find that only your partner remains by your side. They have accompanied you from your school uniform to your wedding dress, from your youth to your white hair, and with a smile, a lifetime has passed. There was a warm light in my youth. To leave no regrets, I hope she can see that I truly, truly like you. Suddenly, I realize how much I depend on someone. When they are gone, everything else feels empty. Do not give up. No matter what tomorrow's path looks like, we can only move forward. If we quit now, all previous efforts will have been in vain. Grit your teeth and persevere. The past is in the past, and there is no right or wrong. You must grasp your own future; do not hand it over to someone else. In the eyes of others, you are sociable and have many friends. But only you know how lonely you truly are. I can no longer empathize with your joys or sorrows. We both gave our hearts once; how can we simply forget? Regardless, I will delete all contact information and start a new life. Society is like a furnace. Initially, we are all iron blocks. Those with enough heat and who endure the hammer will become steel. Those with insufficient heat or excessive heat will become iron slag or molten iron. Everyone has the potential to become steel; it all depends on whether you can endure the strikes at the right time.
