In the break between graduation and going to a new school, the pair of them are free to explore their burning attraction to one another.

So, to prepare herself to enter the madness of the dating pool, she does the only logical thing and hires an escort to teach her how to love (and make love). Michael Phan is gorgeous and caring, seemingly the perfect man for the job. He also can't afford to turn down this job so he gets to work teaching Stella all of the things on her exceedingly detailed lesson plan. Soon, their no-nonsense business arrangement becomes steamy and the lines between professional and personal begin to blur.
