The Grand Apparatus from Brandon Sanderson’s “Cosmere” springs to mind.

The Grand Apparatus is composed of a vast number of rooms all atop and around one another and constantly in motion. [ ] If a denizen needs or wants a room with a particular function such as a bedroom or bathroom, they can make a request to the Apparatus itself and the appropriate room will be brought to adjoin the one currently occupied. Because of the Apparatus’ nature, access to sunlight is infrequent and is only accessed by requesting a room with windows which is moved to the structure’s perimeter upon transferring. Personal possessions are kept in trunks which are moved along with each resident as they transfer from room to room. Because all rooms are shared, there is no concept of ownership of space.

In my 20s I had something of the opposite and had a number of women interested in me who were themselves in relationships, while I was not. Enough of a ratio compared to women who were single who were interested in me (which was not a high number) that I started to wonder why.
I’m not particularly outgoing either. Probably just statistics/chance, but I always wondered if there was something to it I was unconsciously contributing to.
