The usual trope of CEO demanding marriage in exchange for help. Each of the actors does their own part pretty well... they just don't come together as a cast. We are supposed to believe they fall for each other, but he's a jerk and never changes, and she tolerates it because he's had a "tough" life. The one saving grace of this show is that she finally does dump him because he's a jerk. Sadly, they do get back together, in theory because he's finally addressed his psychological issues, but it's not believable. I ended up reading episode summaries rather than watching, and skipped large chunks after about episode 10 or 12.
