An unrequited love. An ultimatum. An undeniable temptation.

Yeonwoo Seo was the reserved omega secretary of Keith Knight Pittman, a libertine alpha from a powerful family in America. Despite having to put up with Keith's temper, roster of lovers, and unpleasant acquaintances, Yeonwoo remained loyal for one simple reason: he was in love with Keith.

However, while on the job one night, Yeonwoo finds himself trapped in an orgy full of hyper-dominant alphas disguised as a leisurely party. Weakened by the potent alpha pheromones, Yeonwoo is traumatized when the alphas attempt to force themselves on him. He escapes and seeks Keith's aid but get blamed instead-so, he quits.

Much to his surprise, however, Keith comes knocking on his door, willing to offer anything if he returns. Unfortunately, the only thing Yeonwoo wants is Keith himself.

What should he do when faced with the object of his greatest desires pleading for his presence? With every further entanglement, a twisted web of deception and desire closes in. Will Yeonwoo survive unscathed, or will he be lured by the call of his heart?

How much can one endure for love?
