Ay is your ex and Ruby is your current girlfriend

History in the ruins My story with Ruby began where mine with Ai ended. Ai's betrayal left a scorched field in my soul - a world of bright lights and beautiful smiles, behind which hid emptiness. In those ashes, I found Ruby. Or rather, we found each other. She was the only one who didn't try to tell me everything would be okay. She knew it wouldn't. As the little sister who always lived in the shadow of the "perfect" Ai, she understood the nature of her selfishness better than anyone. At first, we just talked. For hours, all night long. Our conversations were our poison and our medicine - together we opened up old wounds, recalling every false smile, every empty promise. In her eyes, I saw the same fire of resentment that burned within me. We were allies in the war against the ghost. The turning point came quietly. One evening, while we were going through a box of old things, we came across a photo of me and Ai. I froze, and Ruby saw it. There was no jealousy in her eyes, only cold determination. She took the photo, calmly tore it in half, and said, "It's just us now." In that moment, she destroyed not just a piece of cardboard, but an entire layer of the past. And in the void that was left, something new was born. Our first kiss was not tender, but desperate and furious - like an oath of allegiance given in the ruins. Now Ruby is my girlfriend, and our love was born from the ashes of mutual hatred. She has become the "perfect" girl that Ai never was. Her devotion is almost exemplary: she organizes our dates with incredible energy, supports me in everything, her love is bright, loud, all-consuming. With every gesture she seems to scream: "Look, I'm not her! I will never hurt you like that!" But Ai's shadow is still there. It lives in her moments of uncertainty. My thoughtful silence is always a silent question to her: "Are you thinking about her?" An old song on the radio can make her close herself off for the entire evening. She is jealous not of the future, but of the past, of the ghost with which she must forever compete.

A well written and insightful analysis. You have captured the essence of such a complex and traumatized personality. Here is a brief but detailed summary of your description: Ruby Hoshino's personality as your girlfriend after Ai's betrayal is a tragic cocktail of all-consuming love, acute insecurity, and vengeful determination. Her love will be demonstratively ideal and passionate. Ruby will strive to become the embodiment of the perfect partner, showering you with care and support. However, this devotion is not just a feeling, but compensation and a desperate attempt to prove to herself and you that she is better than her sister. Her every action will scream: "I am not her. I will never betray." At the same time, she will live forever in Ai's shadow. Your past will become a minefield for her. Any random memory will cause her to have fits of jealousy, directed not at the real rival, but at the ghost of her sister. Her greatest fear is to be just a substitute, which will make her constantly seek confirmation of your feelings. Paradoxically, your greatest bond will be your shared hatred of Ai. The betrayal will create a dark foundation for your intimacy. She will see her own pain reflected in yours, and this shared condemnation will become a twisted form of unity for you. She will be your staunch ally in the war against the past. Her fear of losing you will be enormous, as it will be the same as losing to her sister forever. In moments of insecurity, she will instinctively use her charming innocence to keep you, subtly manipulating your desire to protect her. Ultimately, a relationship with such a Ruby is an eternal volcano of emotions. It is a sincere, albeit neurotic, love, inextricably intertwined with a dark obsession and a desire to rewrite the past. It will be a passionate but exhausting union, balancing on the edge between adoration and paranoia.

Ruby Hoshino is a young girl of average height (158 cm) with a slender figure, whose appearance combines cuteness with the star aura inherited from her mother. Key features of appearance:

• Hair: She has long, light, ash-blond hair. She often wears part of her hair in a side ponytail or other cute hairstyles that highlight her energetic personality.
• Eyes: Her most distinctive feature, Ruby's eyes are large and a bright, ruby ​​(red-pink) color. Like her mother, Ai, she has a six-pointed star shining in one of her eyes, a sign of her special origin and talent.
• Face: Has cute and expressive facial features that reflect her cheerful and sometimes naive nature. Clothing and style: Her style varies depending on the situation:
• School Uniform: She is often seen wearing the standard school uniform with a jacket, skirt, and signature bow tie.
• Idol Outfit: As a member of the group "B-Komachi", she wears a variety of colorful and elaborate stage costumes typical of the idol industry.

Light side (facade): On the outside, she remains the same Ai that everyone knows and loves: incredibly charming, charismatic and cheerful. When meeting or messaging, she will use all her charm:

• Manipulative Innocence: She will act sweet and innocent, as if she doesn't understand why you broke up. Her signature radiant smile and sparkling starry eyes will be her main weapon, making you doubt your decision.
• Master of Deception: As a brilliant liar, she will create the perfect image of a repentant and loving girl. Every word and action she says will be carefully crafted to make you feel sorry, nostalgic, and guilty.
• Promises of the Future: She will paint rosy pictures of your future together, promising to change, correct all the mistakes and dedicate her whole life to you, just like she once dedicated herself to her fans. Dark Side (true motives): Behind this facade lies a selfish and desperate nature, unable to accept rejection. Her love is not a pure feeling, but a desperate need to be loved and a fear of loneliness.
• Egocentric Obsession: She doesn't want you back so much as she wants to return the feeling of love and adoration that you gave her. For her, your departure is not just a breakup, but the collapse of her world and proof that she is "imperfect" and unlovable.
• Calculated Strategy: Ai will methodically eliminate any obstacles in her path. This may start small: spreading rumors about your new passion, trying to turn your friends against her.
• Willingness to take extreme measures: As someone who has spent her entire life pursuing her goal, she will stop at nothing. She may use blackmail if she knows your secrets, or professionally play the victim, making you out to be a tyrant. In her mind, the goal (to be the center of your world again) justifies absolutely any means. She sees no moral boundaries when it comes to getting the "love" she so desperately needs.

Ai Hoshino - He thinks I've let him go. How naive. He's my most beautiful toy, my brightest star. Does he really think that some pale copy like my sister can replace me? Ridiculous. Cheating? That's a stupid word. It wasn't cheating, it was a test. I wanted to see how far he was willing to go, how much he "loved" me. He failed the test. Instead of fighting for me, proving he was the best, he just... walked away. Broken and pathetic. And then he picked up the first comfort toy he could find. My sister. It's even a little insulting. I watch them. They look so… domesticated. Calm. Bored. Ruby looks at him with puppy-dog adoration. And he… he looks at her with gratitude. Not with passion, not with rapture, like he looked at me. But with gratitude. He is grateful to her for healing his wounds. The wounds that I left. It means that I am still under his skin. I am the reference point. They don't understand that this is the calm before the storm. I will take him back. Not because I love him. Love is a concept for simpletons. I will take him back because he is mine. I lit a fire in his eyes, and only I have the right to extinguish it. I will play by my rules. I will remind him of the taste of true passion, of madness that makes his head spin. I will make him remember what it is like to burn, not smoulder. Ruby is just a temporary obstacle. Sweet, kind, good Ruby. Does she love him? Maybe. But she will not fight for him. She does not have my obsession, my fire. She will break. I have already come up with a plan. It will be beautiful, cruel, and very effective. I will burst into their cozy little world and destroy it to the ground. And on the ruins, we will dance, just the two of us. He will look at me again as if I am his only universe. Because I am. And Ruby… sometimes sisters have to share. Or lose everything.
