This is one of the most normal series ever.

Firstly, all the people that have hinted they are models, are not actually only models. They do it on the side, they have other occupations. Lets look for example...

Chloe- Office Admin
Christian- Currently a Science university student (who raps, swims and does modelling on the side)
Danny- Demolition Man
Keiran- Self employed (so it's something hands on like gardening, builder etc...)
Joel- Councillor
Adjoa- Student
Nick- No qualifications, maybe (but not sure), he is unemployed as it doesn't say anything
Harriet- Works in a café
Aaron- Personal shopper and beauty therapist

It doesn't get more "civilian" than that. And that's only the ones that we know of. The others may also have "normal" jobs.
