Paid to be His

What happens when you find out your girlfriend has been paid to be with you?

Casey is new in town, just moved because her parents couldn't take good care for her. So, to have money, she works as a piano teacher for Zuri. The daughter of THE Morgan and Kristina Ross.
Just when Luke sees her, he falls for her. Although, since he does have many "dream girls" he goes on a date which ends badly and has become very, very sad. Jessie pays Casey to be with him and he later find out. What happens next?
