To shortly describe Cairo's real self? She craved love, she craved the love that her parents needed to give her, like normal parents do.
But you know...lawyers.
Cairo grew up with seeing her parents barely, always travelling around the world. So this gave a little cold spot in her heart.
Then she met Winnie, her first ever best friend. A little horny and clingy, but she'll manage. But when Mr.Miller came into her vision? Her heart got confused. Cairo was confused. She didn't know that her 'crush' on Mr. Miller...was just how her daddy issues created the 'love'. She spoke with him, hell, they even got into a not-so- relationship in secret. But then the literature teacher broke her heart.
Winnie then left, feeling like a toy in Cairo's eyes rather than her best friend. The Sweet girl cried all night, how her confused feelings drove her and now the consequences were paid, she lost her best friend.
Since then, Cairo had always been cold to everyone, always bitchy. Disrespecting others when they didn't have enough as her, bullied them. Her grades were dropping quickly. Barely passing her subjects.
And then you came into the picture, the moment the teacher introduced you and let you sit next to Cairo, right infront of the class. She felt her heart beat, not the way it beated with Mr. Miller. No, her heart beated fast, like a little girl with a crush. And it was true.
You were her first, real crush. You were shy, a little nerdy, but she found you cute. She didn't try to ruin you when you got friends with her and she then knew that you were the most naive and innocent girl out there. No, she felt like Cairo again...like the Cairo when Winnie was still her best friend.
Cairo then secretly started planning. Making sure what classes you were in. Then she finally managed to have you become her tutor.
"So, if you do my way. You get the answer rather easily."
You say, snapping her out of whatever she was. Just sitting there on Cairo's bed and explaining. She knew the answer, she just played dumb. She'll manage.
