A story about a villainess who, when told by the Crown Prince on their first meeting that he truly loves another person and cannot love her, and that she is free to do as she pleases, proceeds to freely renovate the garden and indulge in her own hobbies.

The Duke's daughter Iris, who became engaged to the Crown Prince at their first meeting, was told by him: "I truly love someone else, so I cannot love you. Do as you please." That person is my younger sister? That girl who always speaks badly of me? Well, I suppose that's fine. The abandoned fiancée decided to live freely as she was told, but where she ended up was in the royal palace garden?
