But an uncharacteristic and unplanned one-night encounter with Lu Xing Chen (Ke Chun), the free-spirited heir to a large family business, leads to enormous confusion. Things go from bad to worse when her firm unwittingly hires Xing Chen to become Liu Su’s new personal secretary, leading to bitterness and hostility. But as they begin to work together, Xing Chen notices a warm side of Liu Su’s personality that she keeps hidden beneath her calculating exterior, while Liu Su is stunned to discover that Xing Chen has a genuine talent for design. Could their animosity give way to respect – or even love?
