Selling a marriage to the billionaire

Emily Mason has run out of a place to live, she doesn't have a good salary to afford an apartment on her own, and if she doesn't get a place soon, she will have to go back to her small town and give up her scholarship.
Nathan Vandenn has it all, the money, the popularity, the luxuries, and a wonderful apartment with an empty room in Kensington, London.
Nathan is willing to take Emily into his apartment, but Nathan doesn't need Emily's money. Nathan needs Emily, Nathan needs to marry her.
If Nathan doesn't marry Emily, Nathan won’t get the vice presidency of Vandenn Industries.
They both need each other, but can they handle this lie without falling in love?
