Elvir is the illegitimate daughter of the king of Fastu, a volcanic nation, and a mother who belongs to the wildcat beastkin race. Despite her birth outside of wedlock, she was granted the rare and exceptional status of princess. This elevated position came with a heavy political expectation: she was arranged to marry Arnold II, the reigning monarch of the powerful nation of Zugvogel. However, this union is far from a fairy tale, as Arnold II is widely feared and known throughout the realm as the "cursed king." Compounding Elvir’s daunting fate is the cruel arrangement surrounding her journey to the altar. Her half-sister Ruby, who has spent years relentlessly tormenting and harassing her, has been assigned to accompany her to the wedding under the guise of serving as her personal maid. Rather than offering support, Ruby’s presence ensures that Elvir will face continued hostility even as she steps into a perilous marriage. Caught between a dreaded groom and a malicious sister, Elvir must navigate a treacherous path where her royal title offers little true protection.
