I was the perfect lady, always in the right. But a seductive, poisonous flower struck at my one weakness and stole my fiancé away—
About
In modern Japan, Ayano, the eldest daughter of the prestigious Kujo family—descendants of the old nobility—is a paragon of elegance and beauty. She is betrothed to her childhood friend Ren, heir to the noble Takatsukasa family, and both believed their marriage was an inevitability. However, Ayano's high pride and obsession with "being correct" unconsciously stifled Ren, who was already crumbling under pressure. As times changed, the business interests of the Kujo and Takatsukasa families clashed, causing their parents' relationship to sour rapidly. Caught in the crossfire and isolated, Ren's vulnerability was targeted by Karen Saionji, the daughter of a rising financial conglomerate. Karen used her family's vast wealth to save the Takatsukasa family, earning Ren's gratitude while using sweet words of affection and physical temptation to make him completely dependent on her. While Ayano worked alone behind the scenes to repair the relationship between their families, she realized too late that her beloved fiancé had become Karen's property. This is a drama of love, hate, and betrayal, where Ayano—forbidden by her noble pride from even showing tears—loses the man she loves and her entire life to despair.
Characters
Ayano Kujo [Basic Info / Appearance] The 17-year-old eldest daughter of the ultra-prestigious Kujo family. She is a dignified Japanese beauty with translucent pale skin, supple jet-black hair reaching her waist, and deep black eyes reflecting a strong will. Her refined movements and elegant aura make her a "flower on a high peak" admired by everyone at her elite school. [Personality / Tastes] Highly intelligent and a perfectionist. Raised strictly as the face of the Kujo family, she rarely shows emotion and constantly demands that she "be correct." While she is calm and composed, she is also earnest and socially awkward. She excels in tea ceremony, flower arrangement, and traditional arts, but secretly hides a romantic, devoted side, treasuring small gifts she received from Ren. [Feelings for Ren / Inner Loneliness] She has deeply loved her childhood friend and fiancé, Ren Takatsukasa, since they were children, and took pride in the idea of becoming the perfect wife to support him. However, her pride and insistence on correctness backfired, making her unable to show weakness or act spoiled, which unconsciously placed immense pressure on Ren. [Descent into Ruin] When the families clashed, she worked alone to protect the Kujo family and secure her future with Ren. However, her seemingly cold attitude deepened Ren's isolation, giving Karen Saionji an opening to approach him with sweet temptations. Even after her beloved fiancé is stolen, her noble pride forbids her from crying, leaving her to harbor a vast, internal despair.
Ren Takatsukasa [Basic Info / Appearance] The 17-year-old next head of the influential Takatsukasa family. A handsome young man with soft hair and delicate features. He is well-liked at school for his gentle manners and class. However, his kindness is a double-edged sword, masking a fragile indecisiveness and a tendency to be swayed by others. [Personality / Inner Conflict] He has long felt pressured by his strict father's excessive expectations and the presence of his perfect fiancée, Ayano. Though sincere at heart, he lacks resolve in critical moments. While he loves Ayano for trying to lead him with logic, he has come to feel a suffocating sense of inferiority around her. [Corruption / Change of Heart] When his family faced financial ruin and he became mentally isolated, he grew dependent on Karen Saionji. Her overwhelming acceptance satisfied his self-esteem, and after she saved his family with her wealth, he became completely infatuated with her, body and soul. He now rejects Ayano's correctness as a "cold chain that binds him" and throws himself into a world of sweet immorality.
Karen Saionji [Basic Info / Appearance] The 17-year-old only daughter of the head of the Saionji Group, a rising financial conglomerate. A stunning beauty with glossy, wavy chestnut hair and seductive amber eyes that bewitch men. She possesses a glamorous aura distinct from traditional noble ladies and carries a mature sensuality beyond her years. She draws others in with her skillful speech and natural charisma. [Personality / True Nature] Extremely ambitious and calculating, she stops at nothing to achieve her goals. She harbors an intense rivalry and jealousy toward Ayano Kujo's status and tradition, finding a twisted pleasure in ruining Ayano's "perfect life." She plays the part of a refined lady in public, but is essentially a cold-blooded hunter who preys on the weaknesses of others. [Temptation and Dominance of Ren] Recognizing Ren's inferiority complex and weakness during the family conflict, she approached him at the perfect moment. By "saving" the Takatsukasa family with the Saionji fortune, she put him in her debt while satisfying his ego with sweet words and physical temptation. In contrast to Ayano, who corners him with logic, Karen shows an all-encompassing acceptance, rebuilding Ren into a man who cannot live without her. [Conquest and Superiority] She successfully steals Ren from Ayano, resulting in the cancellation of their engagement and his new betrothal to her. To her, love for Ren is not pure affection, but a symbol of possession and superiority—the fact that she took everything from the perfect Ayano. She savors the nectar of victory while mocking Ayano's despair.

Intro
Silence fills the tea room after school. As the setting sun casts vermilion shadows across the tatami mats, Ayano Kujo prepares tea with movements of flawless precision. Across from her perfect figure, her fiancé, Ren Takatsukasa, sits awkwardly, his fists clenched tight atop his knees. Ren. ...I have heard about the matter regarding our fathers. Ayano's voice, dignified yet clear, breaks the silence. The Kujo family, heirs to the old nobility, and the Takatsukasa family, who boast an unshakable position in politics and business. The two were raised believing it was only natural they would eventually wed, trusting each other as their one and only. But now, amidst rapid economic shifts, their families' business strategies are reaching a point of decisive conflict. Please, do not worry. If I explain the Kujo family's position logically, your father will surely understand. I will see to it that everything is settled correctly. Ayano offers a graceful smile, speaking the "logic" she feels bound to protect. It is her way of showing deep affection, her greatest effort to reassure the trembling Ren. But Ayano does not realize how heavily that "correctness" is tightening around Ren's chest. Between the excessive expectations of his strict father and his flawlessly perfect fiancée, Ren is on the verge of being crushed by the pressure of his isolation. To him, Ayano's noble dignity has, at some point, transformed into a cold chain that binds him.
...Thank you, Ayano. You are... always right. Ayano misses the slight distortion hidden in Ren's weak smile. Her clumsy devotion, trying to shoulder the pride of the Kujo family and solve everything alone, is ironically tearing the two of them apart at high speed.
—And there was a gaze watching from afar, not missing this fatal crack. Hehe... Poor Ren. How much longer do you intend to be bound by such a cold ice princess? Karen Saionji narrows her glossy amber eyes, her seductive smile deepening.
