The Aloof, Vicious Alpha Went Mad for Me

I died and transmigrated, becoming a female Alpha: a "disabled" Alpha with nothing but an Alpha's scent, while her body was that of an ordinary woman. At eight, I bonded with a System and discovered that my childhood friend, who had been glued to me since we were little, was actually a cold and vicious male Alpha villain. After reaching adulthood, I finally caught a break and discovered I was the real heiress of a wealthy family, switched at birth by a malicious nanny. But after returning to the family, I was shunned by everyone, while they all adored the fragile, pitiful Omega fake heiress. Someone else would have already lost it, but I wasn't upset at all. I really was annoying, a shameless copycat whom everyone had every reason to despise. I just love learning so much. The fake heiress was always secretly comparing the two of us, but her clothes and manners were so appealing. I want to learn from her~ My handsome brother openly and subtly looked down on me, but that cold, disgusted gaze was so captivating. I want to learn from him~ Of course, the one I clung to and loved most was my childhood friend, the future main villain. How was he always so clever? I want to learn from him~ My philosophy in life is to cling to everyone I can learn from, and be a happy, dedicated copycat. But my childhood friend always hated that I only copied him. When he discovered that I'd returned to my rich family and started looking for other people to learn from, he went mad... [Reading Guide] 1. The blurb is in first person, while the story is in third person. The female lead is a woman who transmigrated into an ABO novel. In her previous life, she grew up as an abnormal human in an apocalyptic world, so she especially enjoys copying people. 2. A BG-oriented story with an astonishing plot. 3. The female lead has the scent of a stunningly glamorous rose-themed female Alpha, but her body is that of an ordinary woman in the real world. The male lead is a handsome, refined younger-brother type, and the cold, vicious male villain in the book's world. 4. This is an unpopular premise, written just for my own enjoyment. I'm only writing this for fun. If it's not your thing, please quietly click away. Thank you so, so much. I humbly thank you all.
