This is a short story that I read as part of a story collection. I read it like 10 years ago, but the collection was a bit older. I cannot remember the cover.
In the story, there are people living on a planet, and other people living either on a spaceship or a space station. The main thing is that people in space are either hibernating or experiencing time very slowly relative to ground people, due to effect of a nearby black hole or something. The consequence is while generations pass down on the planet, only a couple of days pass in the space people's lives. Once in generation (or generations), the space people wake up and come downstairs and mingle with the ground people in a kind of ball or meeting.
There are romantic or other relationships being experienced among individuals of spacers. While these relationships or love stories are mundane normal interactions for space people, their actions are scrutinized closely by grounders. After a couple of hours or days, the spacers leave for space. And it is couple of generations for the planet people until they descend again. In this time period the love affairs of space people creates a gigantic body of literature, theories, hypotheses, even followers of thought schools and even rival factions of supporters of different views.
At the beginning of the story I vaguely remember that planet people from rival thought schools are traveling to the descent location and are constantly trying to undermine or stop the other party from reaching to the destination.
This was a very interesting premise of how time difference changes people's perception of the world.
