This enemies-to-lovers fantasy romance follows a strong-willed, sword-wielding heroine who takes control of her own destiny. 

Anna, daughter of the Margrave of Halmich, is tired of the expectations placed on women in court. She has no interest in marrying a nobleman because society expects it of her. Instead, she works hard on her swordsmanship and dreams of joining her father on the battlefield someday. Unfortunately, fate deals her a heavy blow: when the hostile forces of the Kingdom of Albion invade and take the Halmich heir prisoner, she is given to the enemy prince in exchange for her brother's life. 

But even in the face of these tragic circumstances, Anna still has plans of her own: 

"I'll infiltrate their ranks as a tribute, and then... I'll defeat the man who killed my father." 
 

In this world, monsters consume a person's lifespan in exchange for granting their every wish. However, Nea's mysterious "apothecary" monster seems uninterested in consuming hers. 

After wandering into the land of Weem, Nea is offered the illustrious position of Songbearer, and forms a contract with Dino — a monster as beautiful as he is powerful. While Nea adjusts to her role (and Dino's peculiar brand of companionship) she is tasked with the search for the Grimmdoll Chain: an artifact in possession of the elusive Masked Monster. If not her lifespan, what will Dino require of her in exchange for her wishes...?

And to her shock, he accepts.

Despite the strange beginning of their engagement, Arthur is an adoring fiancé to Alice, eager to spoil her with luxurious gifts and earn her affection. But behind his charming smile and solicitous attention lies a deeper intent and focus, hints of a man who has had his eye upon Alice for far longer than he cares to admit…
