Sad sitting in Lamborghini

Vivian was born in a rich family but she isn't like any different spoiled kids. She's born with special brain cells, which can work faster and longer than normal humans. That's why she can remember, that her 'parents' killed her real parents for her.
She always has conflicts with her parents, so she decided to move out.
One day, a new kid, Brooklyn, comes to her class, and she's his 'partner' for the year.
Vivian thought it was going to be the worst time of her life. But that boy brought happiness to her. Will he be able to help her, finding out the truth of her parents' death, or he'll just be a boy, who walks by her life...?

'noone is sad sitting in a Lamborghini'. In her theory, not having one is even happier.
