First of all, the real protagonist of the film is the woman rather than the boxer, and this woman can be regarded as a femme fatale. Because of her jealousy, her sister finally committed suicide, which is a bit far-fetched. In addition, the death of the boxer boss was completely accidental. In fact, no matter which man stood by her side, the result would be the same. The film climaxes after the boxer fails to rescue the woman. The woman only wants to protect herself, not caring about the boxer's fate, but is seen through by the rich. The boxer ran away and finally overpowered the rich man who was chasing him. The end returns to the beginning scene. The woman rushes to the station and kisses the boxer. The film ends.
According to my understanding, the end is the darkest part of the film, and the last kiss is the real killer kiss. In just three days, women's attitudes towards feelings changed three times, and everyone involved in women had a tragic ending. Only the boxer was about to leave for Seattle to start a new life. In the end, the woman appeared, and the boxer was very happy, but what awaited him might be a darker life.
This is not to say how impermanent fate is, but how impermanent this woman is.
