At That Time, It Was Just Commonplace

I have traveled through time, which is actually quite unfortunate. Every step of the way has traces of my previous life. I think I understand it, but actually I don't. Once you have passed by, you often miss it. If you want to look back, it will only be a little more melancholy and helpless. When you are ignorant, the person who loves you will have your head broken; when you are growing up, the person you love will be alienated and cold; when you are mature, remind yourself to grasp what you can grasp, and the clouds will be calm and the wind will be light. Sigh, sigh, sigh, it was just ordinary at that time.
