This is my first one-shot so I hope you like it!

I don't own anything you recognize

(Cissy)

She had always promised she would never leave me.

She broke the promise.

Now where the portrait of Andromeda Black stood on the Black family tapestry remains a black burn mark.

She left me and Bella for a filthy Mudblood.

She left me, Bella, Regulus, Aunt Walburga, Uncle Orion, Mother and, most of all, Father.

It pained him the most, watching his once Pure-blooded princess turn into a Blood-traitor shame of a daughter.

I wish she had stayed.

Andromeda Black ran off with the Mudblood Ted Tonks three weeks after returning to the Black Mansion.

I remember it as though it was yesterday, not two years ago.

Andromeda was called into the study of Father's to tell her she was going to be marrying Lucius Malfoy.

"No. I can't." Andromeda had said.

"What was that, Andromeda?" Father asked.

"I'm not marrying Lucius Malfoy, Father." Andromeda had paused. "I'm marrying Ted Tonks. He proposed to me in the middle of the year."

"The Mudblood Tonks?" Father had said, while his voice had raised.

"Yes."

"Then you are no daughter of mine! Pack a trunk and leave now!" Father had roared.

Then Andromeda came face-to-face to me and Bella one last time. Bella had finished Hogwarts two years earlier and I was in my fifth year.

"Goodbye, Bella." Then she had whispered in Bella's ear "Look after Cissy for me."

Then Bella had pulled a disgusted face and had spat "Of course I will. She is my only sister, I have to watch out for her." Then she had ran to her room.

I had started to cry. Andromeda had pulled me into a hug.

"Goodbye, Cissy. I'm so sorry I'm leaving. Remember this; I'll never forget my baby sister." I had been so upset I hadn't of rejected to being called "baby sister"

"Why did you accept?" I had wept.

"I love him. Goodbye, Cissa. I'll never ever forget you, nor Bella or Regulus or anybody. Especially you."

It was only when she had left I had whispered "You broke the promise."

I hope you like it!

I chose Cissy to be more affected with Andromeda running away, as Bella is quite tough and hardly believed in love.
