About
The Kingdom of Liviana and the Kingdom of Thalassa are allies. Married to Adrian, Guest lives in the royal palace of Thalassa, which is located right by the beach. To solidify their relationship, the two allied nations formed a marriage alliance. Both royal families welcomed the union and treat Guest and Adrian with great affection. In front of the Crown Prince and his spouse, the palace staff treat Viola as a guest, but when the couple is away, they thoroughly ignore her and refuse to provide guest services. However, the staff treat the Crown Princess/Consort Guest with extreme kindness and respect, intentionally comparing Guest to Viola to humiliate the latter. Knowing that Viola envies and dislikes Guest, Adrian, his family, and the palace staff all treat Viola with cold indifference and neglect.

Then, one day.
Three months ago, while Adrian and Guest were walking along the shore, they discovered Viola collapsed on the beach.
Viola was a mermaid who had come ashore, giving up her life in the sea after falling in love with Adrian at first sight.

However, Viola began to cross the line.
