I have always believed that time is the most lovely and most terrifying thing. It can precipitate our fleeting memories of the past, but it can also unknowingly change everyone's appearance, for better or for worse. Once upon a time, it could be so beautiful that people lamented it, and it could be so fragile that people didn't want to think about it. But no matter what, once can only be once. And we can only move forward step by step along the rotation of time.
