I've been thinking about this for a while, based on the series Outlander.

What if you accidentally ended up in the 18th century... At first you don't know yet how you can get back, nor if you actually can. So you have no choice but to stay there. You find a place to stay, work, whatever...
The biggest thing in this story is: you fall in love with someone there. This is THE love that you've been looking for, hoping for, maybe not even expected it to come anymore. And there he/she is! The love of your life!
You are incredibly happy with them, and so are they.
But living there, in that time, comes with many disadvantages: no antiobiotics, doctors, medication, surgery. No electricity, running water, no flushing toilets and showers. No internet, tv, radio, or mobile phone.
For the ladies... no proper bras (for the ladies), having to wear a long dress / skirt ALL the time, no hair conditioner (ouch), no sanitary napkins/tampons.
If you're still at the age of wanting a child: no vaccination, disposable diapers and so on and so forth.

In the meantime you've also figured out how to get back to the now. But that'd mean not being with the love of your life anymore as they can NOT travel with you to the now.

I invite you to really think about this.
What would you do?
Stay or go?
