rosie's rule

All work and a little bit of fun. Roseanne Park, a rich, 27-year-old company CFO, isn't really one for emotional attatchments, the very reason why she never gets into serious, romantic relationships. How could she, when she's way too fond of the single, uncomplicated life?

The night of her friends' engagement party at a luxurious night club in Uptown Manhattan, Rosie crosses paths with a fairly confident and attractive brunette, whom she learns, later on, to be Manhattan's oil heiress, Kim Jisoo. It was just supposed to be a friends-with-benefits sorta thing - not a single string attached - something Rosie made sure Jisoo understood, which she did. And as they went on with their strangely addictive, impossibly dangerous little game, lines between lust and love were drawn, stricly, by a certain rule Rosie decided would keep her in control of everything.

However, when Jisoo seems to be a little too stubborn to keep her agreed promise, the highly-anticipated rich-people-drama starts.
