One Day at a Time - (Season One)

Martina Ruiz had to grow up quickly.
Both of her parents had passed away before she hit seventeen. Her mother's death had officially left Marty and her little brother, Lukas, all alone in the world... but if she was being truly honest with herself... their mother had 'checked out' long before she actually died.
The only constant she had throughout all of this mess was Nick. Sure, Nick had his faults- and was it necessarily wise of her to love a drug addict? Not really, but Marty loved him anyway. She'd had since... well, for a long time, though she hadn't pieced it together until three months ago. Not that it changed much, after all, Marty had always loved him.
Even if they weren't exactly talking right now...
Then the world, which hadn't been an easy place for her to live in, ends.
Everything changes... Except for one thing, really, and that's Nick.
