It means that there is no need for two strangers to love again, and all the passionate lingering is unnecessary. Letting go is the best choice. It's better to miss each other than to meet. Those who have been hurt, seeing each other again can only be more sad, it is better to turn into nostalgia. Although the melody of this song is relatively relaxed, the artistic conception of the lyrics is very cold and helpless. When we don't know how to cherish a warm love, we regret wanting a second time later, but it turns out that it is incomplete and redundant to piece together the broken mirror. Once the passion, once the body temperature, once the simplicity are gone. When they are mature, they can only say goodbye with a smile. It is suggested that lovers who are currently lovelorn should recognize their emotional value and cherish their beautiful marriage, and don't wait until they miss it to regret it!
