When college sweethearts Jung Ji-oh (Hyun Bin) and Joo Joon-young (Song Hye-kyo) get back together after a few years of being apart, they find that the differences that separated them are still very much at play.  Now they are faced with the question of whether they should overcome them together or go their separate ways.
