The performance of missing bridge section in the film is very detailed and specific. The accidental meeting of two strangers, Joe and Susan, from misunderstanding, temptation, understanding to mutual affection, is full of romantic beauty, just like the arrival of passion and love. The film tries to show the beauty of meeting and falling in love here, and highlights the sadness and regret of parting and missing. Although they have all looked back, over and over again, they still missed it, or even died. Although it is sad, it is not regrettable, because they expressed their hearts to each other, which is much better than not having the opportunity to say "I love you". The beauty in front and the farewell in the back are moving. Three times of looking back is love and restraint. Missing is more true to regret.
