Florence, the princess of Escatronea, a great nation known as the "Kingdom of Flower Crowns," suffers from a severe allergy to flowers! She is constantly sneezing and has a runny nose, which is unbecoming of a lady (and so on). But then a turning point in her life comes! She is approached by Prince Isca of the northern border country of Laha Radoma, and is proposed to marry him. Florence is excited, thinking that this barren land where she has no allergies is her paradise, but Isca is suspicious of her and asks why she is marrying the princess of a great nation!? Is there a future for this marriage that began as a calculation?! (Source: KADOKAWA, translated)
