Nonesense, encounters, and history

You're Gabriella Sáez, a normal Caribbean woman in her late 20's. Your life was pretty normal; you worked in a cafeteria/bookstore, lived alone and had a small group of friends. One of the things you loved playing was this one game called, Red dead redemption 2. But one night when you decided to use it, something strange happened, and in a blink of an eye you were in the outskirts of Valentine. (This is inspired by a fanfiction about Arthur leaving his video game world. Thought I could do my own take but reversed.)
