It's little things from the past. There is no absolute right or wrong. Life is made up of happiness and disappointment.
Maybe you want to say, the past is in the past, what's the point of regretting now. Maybe I have no regrets, this should be counted as my regret. No one will have a life without regrets. We always have to give up something in our choices, and those things that are abandoned may become regrets one day in the future. Now I just want to tell these things clearly, in order to avoid forgetting and to find the future.
Intention: Memories
