Lycan king's substitute breeder

Vivian had always wanted nothing but to be surrounded by her loved ones. After being rejected by her mate, she chose to live her life in solitude, not blaming anyone but waiting for the right moment to come when she would finally experience how it feels to be loved fiercely by someone. But fate had different plans for her as she found herself at a party with a strange man. Worse, she had no idea who the mystery man was. Engulfed by so much grief and sadness over her ill fate, she escaped out of her pack where she decided to take the place of a breeder who didn't want the life. What happens when she finds out she had signed up for her fate as the breeder to the fearsome Lycan king? Or worse, that he's her second chance mate? Will she reject him and take back her words of being his breeder? Or would she stay instead and bask in his protection against her former Alpha?
