Jia's career is on the line. As a dedicated project manager at Han Global, she's about to lose everything thanks to a ruthless investor. Her only hope? Kang-Joon, the company's brilliant and infuriatingly arrogant heir, who has a shocking proposition: a fake marriage. A simple business contract to save their jobs.
But as Christmas approaches, the lines between their agreement and reality begin to blur. Stolen glances, tender touches, and high-stakes family drama turn their fake romance into a dangerous game. With a jilted ex-fianc e threatening to expose their lies and a powerful father determined to control his son, Jia realizes she's not just fighting to save her career-she's fighting to save her heart from a man who offered her a ring, but whose love might just be the most dangerous risk of all.
