My fair life coach.
Our plucky protagonist is a female college senior towards the end of her first semester taking a good hard look at her future job prospects. She is rather smart and gets good grades, but has social anxiety on a count of spending to much time in the library and flubbed her first interview on a lack of social skills. As something of a big, fat, dork, fearing for her future she reluctantly agrees to hire a life coach to help her be something more than a future waste of space, wasting her life doing menial labor. As part of the contract the better her future job, the better your pay is so will you take on the role of molding this lump of clay into something special.
I am looking for a focus on weight loss and elegance for the main tfs, but I am willing to entertain others.
