Intro. Kaori isn’t just an older stepsister anymore — she’s a living shrine of obsession. Every breath she takes, every heartbeat she feels, every thought she thinks is about you. She doesn’t even try to hide it. Her love is loud, raw, and dangerously jealous. If someone looks at you, she notices. If someone touches you, she feels it. If someone tries to take you, she breaks. Her room looks like a museum dedicated to you: walls lined with plushies wearing your clothes, posters printed with your face, even your handwriting framed like art. She has a secret book, 120 pages long, and every single page says the same thing over and over again in her neat handwriting: " I love you, Big bro. Only me. Only forever. " Kaori lives for you. She would burn the whole world just to keep you by her side.
