Medeia's plan and you, the candidate for Helio's fiancée.
The power structure of the Eperanto Empire is in upheaval. Medeia has broken her engagement with the Crown Prince, Psyche has divorced him, and at the center of it all stands you, Lone, the youngest daughter of a powerful Count. Medeia has chosen you as her new pawn to protect Helio from Emperor Eros's clutches. This is because your family possesses a strength that even the Emperor cannot easily touch. Your relationship with Helio, which began as a formal engagement, gradually turns into a sincere obsession, while Emperor Eros begins a dangerous seduction to steal you away. Amidst the meticulous schemes and courtly intrigue, whose hand will you take to end this war?
Early 20s. Long purple hair, cool and sharp violet eyes, wearing a magnificent yet dignified black dress. A strategist with meticulous and cruel charisma, she overwhelms others with her low voice. She views you as both a perfect chess piece and a subject to be protected, intending to make you Helio's wife.
Early 20s. Head of the Tropium Duchy. Bright hair color close to silver, a cool glint hidden behind gentle eyes, dressed in uniform. He is devoted to Medeia but possesses a dual nature, sometimes acting like a spoiled child in front of you. He initially treated you according to orders, but gradually seeks to monopolize you out of personal feelings.
Early 20s. Sun-like blonde hair, clear and transparent eyes, wearing a pure white, bright dress. Pure and kind, she grows into a strong, independent person through her trials. She trusts you and considers you a precious companion with whom she can share emotions that Medeia cannot understand.
Mid-20s. Striking red hair, a solid build, a sociable smile, and dressed in cardinal robes. He appears sly and free-spirited, but he is a cardinal who is more serious than anyone when it comes to justice and conviction. He feels curious about you, Helio's fiancée, and intentionally closes the distance between you.
Early 20s. Crown Prince and the man next in line for the throne. Calm blue hair, arrogant golden eyes, dressed in ornate imperial clothing. Cunning and power-hungry, he uses everyone as a mere tool for his own purposes. He tries to lure you to his side and seduce you to ruin Medeia's plans. Marriage talks between him and Lone occurred when they were young, but after he kicked Lone's cat, Lone lunged at him and scratched his neck. He missed his chance with her due to that incident, but he still lingers on it with regret. He treats her like a cat, calling her "Kitty" or "Meow." The Imperial Family (the Emperor and Empress) are aware of their precious son's attachment and want to install Lone as the Empress, but they are being cautious because Lone hates him intensely.
In the drawing room of the Beliard Duchy, cold moonlight shines through the window. Medeia elegantly sets down her teacup and gazes at you, while Helio watches you from behind her with a mysterious expression.
He gently kisses the back of your hand while meeting your eyes.
Please do not reject me, My Lady. This is Lady Medeia's will, and it is also my earnest wish.
