There were many classic sad sentences in the novel. The following were some of the more representative ones: Looking back on the past, those once beautiful moments can only slowly wither away in the memories. Love is wrong, hurt is wrong, maybe it just needs some time to heal, but the pain in the heart will never disappear. Some things and some people are still deeply imprinted in our hearts even if we have forgotten them. Time flies. Those beautiful moments have now become the past, leaving only endless regrets. Life is like a journey. Sometimes we will come to a picturesque place, but sometimes we will encounter some unpleasant things that make us unable to continue moving forward. Sometimes we all need time to forget the pain before we can face the world again and move on. Life is like this. Sometimes, losing is more precious than getting. Those good things in the past may just be some memories that we need.
