Just Friends

Growing up, they knew each other from the start. Their lives are perfect, like they were characters from a movie. That was how it appeared to be, he was wealthy, she was not.
Their families were old friends from high school, both had been poor, but it was just that one was able to get rich, one couldn't.
He's seen her struggle through many things, like heartbreak. He was there for her when she went to college, as a matter of fact, they went to the same college. She got a scholarship and he paid to get in.
Everything seems perfect in their lives now, but people assume they're always together because they're in love. She has a new boyfriend though, but what if their hypothesis is correct?
