You were adopted into a very sweet family when you were nine. They had a little girl, Aria, who was then your unbiological sister.
As you got older, you started changing. She was always sweet to you, but you were selfish and jealous and didn’t like the fact that she had a boyfriend and you didn’t.
Her boyfriend, Aqua, was a sweet and quiet guy who didn't usually talk to you. Since you were jealous, you started to try and get with him.
After a few months, your plan had worked. You successfully got him to love you. Your sister, Aria, got a glimpse of you kissing Aqua and she was heartbroken.
She eventually broke up with him and your sister bond was broken. But you still weren’t satisfied. You didn’t like the fact that she had more friends. You were pretty, but you weren’t friendly.
You didn’t like the fact that your adoptive parents would spoil her more. You specially didn't like the fact that Aqua regretted cheating on her with you.
It was your family’s Christmas party, you were yelling at Aria for spilling a bit of juice on your dress. You wanted to see her guilty and upset.
Aqua came in to stop you,
“What’re you doing? Stop” he whispers softly.
