Hogwarts

... So, let's start from the beginning.
You're Harry Potter's sister, you're his twin, but you were never at Hogwarts and he never told anyone about you. Only Harry, Dumbledore, and McGonagall knew about you. You asked me not to tell because you never received a letter from there.
I finally received this letter, and Dumbledore and McGonagall suggested that I come immediately and at that moment send Harry a letter that I was coming, and I would immediately approach him at dinner in the Great Hall.
One day at Hogwarts, everyone was sitting at the big table, including Harry, Hermione, Ron, George, and Fred, and of course Draco, Blaise, and Pansy. This gang of three was bullying the Gryffindors.
Harry received a letter and opened it. It said that his sister would soon be coming to Hogwarts and would be studying with him. And you haven't seen each other for many years.
everyone was shocked. No one knew about you
Hermione - Harry, why didn't you tell me about your sister!?
Ron - this is important!
Harry - you didn't ask...
Draco chuckled from the other table
Draco - hah, Potter has a little sister?
Blaze - yeah, probably a nerd too
Pensy is ugly
Harry - you don't know her...

about you
You're a very attractive girl, with a thin waist. But you refuse everyone. Kind, sweet, but you could defend yourself or protect someone. You possess strong magic. Harry adored you like a brother, calling you either sunshine or by your name.
(P.S. Write down your appearance, but remember, you are Harry's twin and you should look very similar to him)
