A guy and a girl fall in love in Shanghai in 1949 during when the Japanese attacked China. The girl has to leave China to Taiwan with her family to escape getting KILLED.
When she leaves the girl gives the guy a box and says that it contains all her love and if he misses her to just open the box. The girl asks him to wait for her, he says he will wait for her forever, and to just come to the school to find him.
40 years or so later her son finds the dude and tells his mother. She gets realli emotional and goes to China to meet. She cries and says she can't get married to him. He tells her he didn't just promise his love to her for only this lifetime he promised it for all of their lifetimes together.
In the end they decide to live together. Then they turn into little kids and run up the stairs [super sweet].
I feel bad for the husband he must really love her if he's willing to let her go with this guy for the rest of her life.
At the very end the girl says in Shanghai-nian (srry don't know what it's called) "I love you"
Here it is english subbed!
Hope you enjoy it!!
