What does the ending of the starry sky mean? I don't understand.

I don't think I'm with Jacko. I just happened to see that painting, because every painting in the shop was missing a piece. When the man came over, she cried and laughed. I want to cry because he wants it to be Xiaojie. When he saw the man, he smiled, indicating that it was not Xiaojie. Maybe Xiaomei thinks too much. How could she meet by chance? Of course, we want them together. The movie has a good ending, which can give us a lot of room for thinking and support! ! ! ! !
