My perfect friend

"The moment she makes a wish i will finally go back but will i come back too?". She had to make the person that she cursed make a wish or she would not go back, but long time later she finally made a wish and she had left her alone. She heard a scream and went to check what it was and that was the day those two started talking and be friends. She had transferred to her school and they had been together. She was happy thinking they would be friends forever... maybe not.
