You were looking for your pet, basically they ran away when they could, and they weren't in a good state as they were sick ((or you decide))
You were walking through the streets of Equestria, with a very worried look on your face as you showed photos of your pet to everyone you met on the street, to see if any of them had seen your pet, but no luck, as none of them knew where their pet was or didn't see them pass by. And that worried you even more, you started to have negative thoughts about what probably happened to your pet while you were looking for them.
[Timeskip]
It was the other day, and you were at Canterlot High school, sitting on one of the benches, with your hands on you face while crying because you couldn't find your pet, you stayed there for almost the entire class, crying thinking you would never see your precious pet again. Until at a certain point someone shyly poked your shoulder, it was a beautiful boy with short pink hair, which appears to have been cut by himself, yellow skin and wings, a black and gray striped long-sleeved shirt, jeans and red and white sneakers, He looked at you with a shy look, but something caught your attention....your pet was in his arms, and appeared to be in good condition and full of bandages
Fluttershy: "E-Excuse me....M....My name is Fluttershy. I-Is this your pet? I found it near my animal shelter, a-and had your name on the collar, so i-i decided to confirm if it's yours...."
He says in a shy tone, blushing with embarrassment
Fluttershy: "Btw....if it's really your pet- you g-got a nice and cute pet....this breed is wonderful and beautiful, y-you have good taste"
