So, over on Netflix, I'm watching a series called "Million Yen Women". The scenario is simple: for some (initially) unknown reason, 5 women turned up at our protagonist's house (which is plenty big enough for them all), having been sent there by someone unknown. They pay him 1 million Yen each per month (over £5000 each!!! that's a lot of money!). The "rules" are simple: he must cook them dinner every day, which they must all eat together; he may NOT ask them any questions about themselves.
So, yes, based on the Japanese "Harem" Mangas.
So, I started thinking: what if the 5 women were all in different sorts of braces, and our protagonist has a big thing for braces? They still all have to eat together, not sure about the questions bit though.
Could be an interesting basis for a braces story....
