This is a story about nostalgia. In those years, the friends we spent day and night with are now far apart, even separated by yin and yang. The lover we longed for in those years is now married to another woman and has children. In those years, we made promises to heaven. The vows made in Yahaijiao have now disappeared, leaving only the past sentimentality; the stars we chased with passion in those years are now old and faltering; the old songs we sang heartbreakingly in those years are now dusty in our hearts and we dare not sing them!
Only when you have lost can you learn to cherish, only when you have missed can you think of attachment, and only when you have left can you think of going back...
This feeling can be recalled later, but it was already at a loss at that time!
