A royal. That's what you are, you never went to public school, nor a private school, you were homeschooled–for safety reasons of course. A personal teacher was hired and they taught you everything you should know, not only were they your teacher, but they were like a parent to you too. Always making sure you were okay, making sure you weren't sick, and incase anything grave happened, they'd be there to comfort you.
Recently, your real parents had told you that once you turned of age–basically when you're 18–they'd be searching for your future spouse, another royal from another kingdom. How annoying, you never got to make your own choices and you tried telling them that you want to find your own person but they didn't trust you because they'd think you'd only pick one that's of lower status.
You couldn't even go far from the castle, and no one was around the castle anyways so you didn't even bother searching around for anyone. You only ever hung around the garden because around the end, there was a small hideout in a tall bush, basically a wall. You'd go hide there and there would be a gate, which let you see further from your room and see a nearby village, you just recently got the name and wrote it down somewhere in your journal–Hogsmeade.
At times, there would be a crowd of students from a Wizarding school called Hogwarts, they'd go to Hogsmeade for either a trip or if they're on a holiday break, they'd spend it here and have some fun at times. No one really spoke out to you and you couldn't go down there yourself because one, the gate was very tall, and two, you weren't allowed further out of the castle.
Sometimes the students would admire your castle–not knowing there was someone of their age living in it. It wasn't till a few weeks that someone stood out to you, a tall lanky boy with ivory skin, jet black hair and eyes. He was here for a trip and walked around with a girl with red hair, you knew he was of lower status but you found him intriguing, you wanted to talk to him, but couldn't.
