As you can guess she's a very generous pony. She doesn't have much, she works at a local hotel and cafe, and she lives in flat in the massive Equestrian city of Manehatten. She feels like an outlier a lot of the time, a cutiemarkless goat pony amidst a city full of normal ponies. It also doesn't help that she comes from a very small town that is nestled in the middle of mountains..in the middle of nowhere...all alone. Precilla is an only child. She had no friends. Her parents were very, very strict and controlling, and when they decided that she would be the one to take up the family business, she fled. Of all the places she could have chosen to live, she chose Manehatten, it was the most different from her home. Precilla is a pony that doesn't adapt easily, she's stubborn and not used to changing her ways, however, if you don't change in Manehatten, it will chew you up and spit you out. So, Precilla changed, she became less gullible, more sceptical. Also, if you're not an extreme neat freak get ready to see the roaches. 

One day, after a particularly tough shift at the cafe, it starts to rain. She always walks home a different way, its safer and more interesting that way. Everything is perfectly normal, until she looks across the street and sees a unicorn, with light pink hair and a ratty blanket, just laying on the sidewalk, in the rain. Ponies were ignoring the unicorn, some even nearly stepping on her. Precilla crossed the street, and put her umbrella over the pony, and they looked up at her. Precilla asked if she might like to come to her house and have some tea. The unicorns name was Itami. 

Itami and Precilla saw each other all the time after that. First it was just a wave when they walked past each other, then it was Precilla inviting her to walk with her, then Precilla inviting Itami to come have some cake, then Itami crashing at Precilla's house more and more often. They quickly became roommates, then best friends. It eventually develops into a very hesitant romance, Precilla having never had a significant other, or a real friend for that matter, was very, very confused and blushy. Its mildly awkward and hijinks ensue. After awhile, Itami plucks up the guts to ask Precilla on a date, they went for noodles, and Itami realizes that Precilla is actually a whole ass pig. Fuckin adorable, immaculate, 10/10, 100% baby material. 

From there they began to date, Itami moved in, she got a job, and then they were both able to afford a better apartment. They became a family. Eventually Itami proposes, and Precilla obviously says yes, they get married, Precilla's parents are not invited, but sent a picture of the happy couple in the mail. Precilla is still working the two jobs at this point, and at her Cafe gig she meets a singer named Dottie, and when they begin selling a new type of tea, she makes friends with a tea merchant named Chai, and his boyfriend Lloyd. A shaky friend group forms. Dottie makes it big, and Itami becomes her body guard, and main poster designer. As the two are travelling around the country on her tour, Precilla discovers that she has no hobbies and that she's very bored, and decides to attempt to learn about sewing. Turns out that she's actually very good at it. The precise measurements, and the stitches you have to learn are lots of fun to her. Problem is, she's not really a fashionista, and doesn't have many original ideas. Precilla decides to further her education, and she begins taking classes, and eventually applies to a fashion academy. She gets in, excels, and graduates. 

Itami returns from the tour, and comes to find out that Precilla has found a new passion, and wants desperately to support her in any way she can. She makes posters and flyers advertising Precilla's small online boutique, and orders come flying in. Precilla can quit her job at the hotel. Chai, Lloyd, and Dottie all model for Precilla's website. The store is a success!
