Margaret Montgomery is one step away from being the CEO of Monty&Co. Trading Enterprise when an ultimatum was placed upon her; marry Cole Noir or lose all her eight-years worth of hard work. Of course the marriage between them is nothing more than a way to secure the merger between two companies. Margaret is willing to do absolutely anything to achieve her goal but Cole is a different story. Forced to leave the girl he loves to ensure her safety, Margaret and Cole's marriage is nothing but a cold partnership that has no way out. As Cole secretly meets with the woman he loves, Margaret can't help but feel like she's the mistress rather than the wife.
