Grace, the daughter of a prestigious noble family in the Kingdom of Saint Port, suffered a cruel betrayal at the hands of her fiancé, Prince Lucas. After being abandoned, disowned, and even forced into becoming a courtesan, Grace chooses an unexpected ally for her revenge: Alexander, the tyrannical emperor of the Solvalence Empire. "And what benefit would I gain from supporting you?" "I can fulfill your deepest desires." What began as a purely calculated alliance for mutual gain takes an unexpected turn. But Your Majesty... why do you summon me to your chambers every night? Thus begins the dangerous yet sweet revenge tale of Grace, a captivating avenger who has lost everything, and Alex, a devoted yet unhinged emperor (or perhaps a large, loyal wild dog?).
