I recently watched an episode of Midnight Diner: Tokyo Stories on Netflix, season 2 episode 4. It was featuring an ex-model in Tokyo who was invited to a VIP event where "rich CEOs" would attend. Very similar to what you described, in some ways. The episode also explores a bit about the personal aspect of that sort of life, but very lightly. It seems to be a thing in Tokyo, too.
