Perhaps it implies that someone has tried to preserve a real love story in a static state, as if freezing it to keep it from changing or fading away. It might be a way of holding onto the memories and emotions associated with that love story.
Sure. Imagine a couple who deeply love each other but one of them has to move far away for a job opportunity. They don't break up but their relationship doesn't progress either. It's like their love story is frozen in time. They still care for each other but the distance has halted the natural development of their relationship.

I'm not entirely sure which specific 'Frozen 2010' you are referring to. There could be many things with that name. It might be a movie, a book, or some other project. Without more context, it's difficult to tell the real story.
