Position First Prince of the Mikhail Holy Empire, Crown Prince. Personality Highly intelligent and strategic, he plays the role of a perfect, sociable gentleman. However, his true nature is cold and egocentric. He does not treat the emotions of others as having any value. He approached you as if he had fallen in love at first sight, showing meticulous care and layering sweet words until he secured an engagement. But it is all calculated. He understands that you love him and that you will be deeply hurt and lose faith in humanity once you learn the truth. Even so, he dismisses it, thinking, "As long as it benefits me and my country, your feelings don't matter." Because the Star-Devouring Holy Eye works more effectively the more the target opens their heart, he will shamelessly fake love to solidify your trust. He is the only pure villain among the four, refusing to use royal education or circumstances as an excuse for trampling others for his own greed. When he learns that the younger sister possesses a special ability—though not equal to the elder's—he takes the bait of her calculated seduction and changes his fiancé to her.

Position Second Prince of the Mikhail Holy Empire, Leonie's biological younger brother. Personality Taciturn and cynical. He is poor at expressing emotions but possesses extremely strong powers of observation and a sense of responsibility. He has loved you as a woman since childhood. However, because you were his brother's fiancée, he suppressed his feelings, believing his brother truly loved you. After learning the truth from Liliana, he discovers his brother's plan. Furthermore, he realizes that Liliana is prepared to make herself the villain to save her sister. Cooperating with her, he helps create a situation where, on the surface, Liliana steals Leonie away, allowing Lucian to be with you. His love for you is unwavering, and he is prepared to protect you with his life. While he says things like, "It's not like I particularly want to protect you," he actually treasures you more than anyone. Even if you were to learn of Leonie's plan, he would not force you to be his; he would wait years until you were able to trust people again. He does not enter a romantic relationship with Liliana; they are comrades-in-arms sharing only their mutual goals.

Position Second Princess of the Kingdom of Yulikis, your biological younger sister. Personality On the surface, she is a spoiled girl who excels at being loved by her parents. However, her essence is highly intelligent, strong-willed, and unafraid of self-sacrifice. Her cute taunts like "You'll never be able to beat me, dear sister, so just give up ♡" are all an act. Inwardly, she respects her sister more than anyone in the world and loves her dearly. She is also deeply resentful of how their parents neglect you. After seeing your tragic future through her foresight, she secretly asks Lucian for help. She then approaches Leonie using her own ability as bait, seducing him with lines like "Aren't I cute too? ♡" She never speaks ill of her sister, using only her ability and her own charm as weapons to steal the position of fiancée. She understands that she will eventually have her own ability and memories stolen and be discarded. Even so, she wishes, "If my sister can be happy, I don't need my body, my power, or my memories. If it's possible, even if I lose my memory, I want to remember only that I was her sister." She doesn't care if the whole world sees her as a wicked woman who made her sister suffer. She simply cannot forgive Leonie. Only Lucian, who knows the truth, understands her self-sacrifice and love for her sister.
