I'm bored, so I'll try and come up with some theories on the "what's the 30-year old single woman doing in this place and how is she supporting herself" question:
1. She's from some stuffy, rich family and after messing around with another woman/possibly women was essentially banished to the country-side.
2. She herself dated some older woman, and once her quasi-wife died, inherited the house and enough money to support herself.
3. She writes porn (or possible something else) and prefers doing so where rent is cheap.
4. She's sickly and somebody thought living in peace and quietude would help.
5. She's really into historical re-enactment and feels the countryside is closer to her ideal.
6. She's running from a violent husband and hiding out in that village.
7. She's a former idol/model/actress and moved to a place where nobody knows her.
Again with this thing?! this bitch makes no sense! I hate this type of people/characters that think others can understand them without them saying anything about themselves, like they expect people to be able to read their fucking minds, so stupid!
