What is the meaning of Jang Woo's One Man's End of Days MV?

It looks like it's this old man's memories~

It should be that when he was young and with his beloved, he was happy at the beginning.

But for the sake of life, the woman became a dancer or he misunderstood her.

Unfortunately, when he understands everything, the woman died

The token of love that he gave her, the jade bracelet, was also broken~~~

I am also looking at the surface of the meaning of the meaning of the deeper meaning can not be seen

Cleanly put, it is the upstairs said: on the Shanghai's tragic love story!
