Stinging Soul

If life can start over, will he and she choose not to know each other, not to know each other, not to love each other? If time can start over, will he and she choose not to know each other anymore? There is no way back in life, just like there is no experience in life again, and time cannot be turned back. If possible, I choose to be an hourglass, because even if time passes, you can start over again. Can this restore a broken heart?
