We will miss a lot in our own willfulness and regret it after the situation has changed, but it is already like smoke in the past. Maybe he is worried and entangled, maybe he sighs with regret.
At some point, I will look back on the past and realize that I was young and ignorant, and those mistakes I made became mistakes. I will care about if, if I could do this at that time, the ending would be better. In the end, after recalling it again and again, I will lament that the past is hard to recall.
This is a story about a young person waiting for adulthood, and there will be no expected miracles. Some people and some things may be destined to be at odds with each other. We cannot guess what is left behind by the people and things that passed by. But we will gradually mature through these experiences, learn to see and cherish what we have around us, and then understand what happiness we want...
And my hope... Although obviously unrealistic, I still hope that everyone can be happy...
