50 shades of salmon

A very successful business man (Natsu) takes a liking to a college student (Lucy) after she interviewed him for a project in her class for aspiring writers. After they meet he gives her a proposition of where he takes care of every and anything she needs while showering her in luxuries if she does a small favor for him every once in a while. It seems pretty simple until feelings, mistresses, exes, and crazy fans get in the way.
