Imagine that you had been in the cinema watching this one movie.
And then the next week, your crush comes over to you and asks if you want to go to the cinema with them, and then you find out that they are planning on watching that one movie that you had watched.
well... this is based on some story, where a boy told his psychologist (or something like that) that this one girl asked him if he wanted to watch that one movie with her, but he said no because he had seen that movie.
And when the psychologist asked if she was pretty, he said yes and then he regretted saying no to that girl.
I guess that in that situation, if it was a movie that I would refuse to rewatch, I would maybe have asked if we could watch a different movie together, or maybe go on a different kind of date.
