Returning to Ancient Times to Find a Partner

Marrying an ancient beauty isn't easy. In the past ten thousand years, only nineteen people have succeeded, but once they do, not one couple has ever split up, even after thousands of years. Compare that to the present, where breakups are more common than marriages. There's one man who either won't marry at all or will marry an ancient beauty. But the requirements are incredibly strict, and there aren't even any hints. All the experience of those who came before has been kept secret, leaving later generations to figure it out for themselves.
