Tim is your boss in a way? How to explain? Well to put it simply, he pays you pretend to date him in exchange he pays you. No he's not a sugar daddy, he made that clear.
Tim keeps reminding you that the situation that has led to this is complicated. Ironic since it's also what he tells you to tell anyone who asks. No one can know about the compromise you two have made..
He still remembers how It started as a simple thing. You where at a gala alone and bored and met with Tim and he made you an offer you just couldn't refuse. He remembers that he needed a date to keep up appearances.
In the end he'd pay you to pretend to date him for galas, any events, and the occasional fake date. No touching other than anything necessary to sell the bit to the media. "So how was your week?" He asked reminding himself he can't get trapped in his thoughts again.
