give me love.

Her name is Cadence, Cadence Edwards.
She's the daughter of a very successful businessman. She belongs to the higher class and she has everything a girl could ever want. She's even engaged and about to get married, to a man she doesn't love.

Gavin, her fiancé is the son of her father's closest friends. They were always with each other, since their families spent a lot of a time together. And one day their parents decided that they should just get married already, since "they obviously are meant for each other"
It didn't take long, a couple of meetings in her father's office and about a month later Gavin got down on one knee and proposed on her 19th birthday.

But spending the rest of your life with someone you do not love isn't exactly right.
And she finally realizes that when she meets Justin, and from there nothing will ever be the same again.
