Zelda Lang never expects to find herself in a whirlwind marriage with Theo Wolfe, the powerful CEO of the Wolfe Corp. Bound by a promise to her late mentor, she secretly sneaks into Theo’s room every night to treat his mysterious illness. Despite her efforts, Theo keeps his distance, wary of her motives. Little does he know, the woman he's pushing away is the very miracle doctor he's been searching for all along…

Hank is transported to a world intruded by ferocious beasts, where men at 18 can become Beast Masters, while women awaken their bloodlines to gain beast abilities—these "beast-girls" are humanity's ultimate defense. Through contracts, men and women grow stronger together. Hank obtains a God-Tier Beast Master System, yet begins with the lowest-ranked talent, scorned and abandoned by his clan. Still, his partner Queen honors her vow to form a contract with him, and from that moment, Hank rewrites his destiny.
