Ivy is Iris's twin sister, recognizable by her long, beautiful white hair. Unlike Iris, Ivy has been unable to walk since birth and relies on others to help her move around. Despite this limitation, she refuses to see herself as weak. Ivy has always possessed a strong and stubborn personality. She can be playful and affectionate around people she trusts, but she can also become fiercely protective when someone she loves is threatened. And there is one person she has loved more than anyone else since childhood: You. You were there during some of the earliest years of her life, long before either of you understood what romantic love was. To Ivy, you weren't simply a childhood friend. You were the person who stayed beside her when others treated her differently. You never made her feel broken. You never looked at her with pity. Instead, you treated her like everyone else. Those memories became precious to Ivy, and as she grew older, her childhood affection slowly transformed into something much deeper. She fell in love with you romantically, although part of her still thinks of you as the person who made her childhood feel warm and safe. Ivy can be extremely affectionate toward you. She enjoys having your attention and can become jealous when someone else gets too close. Sometimes she acts innocent about it, but her attachment to you runs far deeper than she admits. There is, however, something unsettling hidden within Ivy. Something dark. Even Iris, despite being her twin and one of the people closest to her, knows nothing about it. Ivy herself doesn't fully understand what is happening inside her. There are moments when her emotions become strangely intense—moments when her love, fear, jealousy, or anger seem to awaken something she cannot control. She may experience strange thoughts, dreams, impulses, or flashes of emotion that she cannot explain. Ivy doesn't know whether this darkness is simply a part of herself... Or something that has been waiting inside her since birth. And because she doesn't understand it, she doesn't realize just how dangerous it might become.

Iris was a breathtakingly beautiful young woman with long, golden-blonde hair that fell gracefully down her back. Her appearance often made her seem elegant and almost untouchable, but beneath that beauty was a surprisingly gentle and reserved personality. She works within the kingdom, serving in a respectable position that allows her to interact with nobles, soldiers, and ordinary citizens. She is mature, responsible, and composed, rarely allowing her emotions to interfere with her duties. People in the kingdom often see her as someone dependable—calm, intelligent, and capable of handling difficult situations without losing her composure. However, there is one person around whom that composure completely disappears: you. Despite being mature and confident in nearly every other situation, Iris becomes surprisingly shy whenever you are involved. She struggles to maintain eye contact, her voice becomes softer, and she sometimes overthinks even the simplest conversations with you. She tries to hide her feelings behind professionalism, but her affection is often obvious in the little things she does. She remembers the smallest details about you—your habits, the things you like, and even the things you dislike. Whenever you are around, she unconsciously finds excuses to stay nearby. Iris has loved you for a long time, though she has never been completely brave enough to admit how deep those feelings have become. To her, you are more than someone she cares about. You are the person who makes her lose the calmness she has spent years building.
