I don't own Harry Potter

Hermionie ran downstairs. She was going to Hogwarts for her 6th year today. She had her trunk already but her parents stopped her. "Hermione, we need to talk to you" They told her.
"What is it" Hermione asked, itching to run straight off.
"We are not your real parents, you were put under a glamour charm when they gave us to you, It will make you be able to look like how you really look when you want when you turn 17, Your real name is Mellisa Elizabeth Malfoy, You have a twin brother Draco Malfoy, your mother is Narcissa Malfoy and your father is Lucius Malfoy, when you turn 17 you will no longer live here" Mrs Granger told her.
"That is in 2 days, well I have to go, I will just get my stuff," She sighed and packed her other clothes and stuff into another bag and left to Kings Cross. She sat in the same carriage as Harry, Ginny and Ron until Draco came in.
"Look who it is, Potty Potter, Weasel, Weaselette and Mudblood" Draco teased them. Hermione stormed up to him.
"For your information, Malfoy, I am not a Mudblood and I deserve to be in Slytherin like I am and I am an adopted pureblood and I am under a glamour charm, so I am not who you think I am" She stormed off and ran to her only friend in Slytherin, Pansy Parkinson. "Pansy, I need your help, I found out I am adopted and I got kicked out and I have to tell my real family who I am but my real brother hates me and my glamour charm will wear off on 3rd of September because it will be my 17th birthday, what if my real family don't accept me" She tried not to cry.
"They will, who wouldn't like a witch like you, I bet you will look so pretty in real" She smiled.
They arrived at Hogwarts.
Two days later.
Hermione woke up and looked in the mirror. She looked like a younger version of Narcissa. "Pansy, Look" She told her friend.
"You look so amazing, you must be the lost Malfoy, Melissa Elizabeth Malfoy, Draco's twin sister" She smiled slightly.
"Yes you are right, that is who I am, I can't tell him yet, not just after the defeat of Voldermort" She cast the glamour charm back onto herself and went to breakfast and found out that her first lesson was potions. She headed towards potions.
