More or less in a person's life, there will be regrets of one kind or another; it may be because of one person, or it may be because of a group of people. There is love, friendship, family affection...
It may be because of the cowardice and cowardice in the past, or it may be because of external forces that cannot be resisted. I used to be crazy about it and heartbroken. After all the vicissitudes of life, when I look back, all that is left is... A relieved smile and indescribable emotions in my heart.
Those past are like fireworks in life, although they are short-lived, they are unforgettable. If you are lucky, you will feel a beautiful scenery after watching it; if you are unlucky, you will accidentally be blinded by the dust carried by the fireworks while watching it, leaving a scar from then on.
Purpose: Recall the past, but still look to the future
