Which Manga Series Popularized The Problematic Sister Trope?

My older sister, Lucy Wheeler, is an extremely sensitive person. She'll burst into tears immediately if her doll is dirty or if a cream puff bursts in advance. In order to maintain peace in the household, my parents will fulfill any of Lucy's wishes endlessly. Since she doesn't like me at all, my parents don't hesitate to kick me back to my grandparents' home in the countryside. Later on, Grandpa and Grandma pass away one after the other, leaving me with no choice but to go home to my parents and Lucy. That's when everyone sets up 3672 house rules for me to follow. Since Lucy loves blueberries, I'm not allowed to touch any of them. Since Lucy loves dresses, I'm not allowed to look prettier than her. After undergoing 20 years of torment, I end up contracting breast cancer, resulting in my tragic death. When I open my eyes again, I've returned to the first day I've gotten home after my grandparents' passing. Lucy is extremely sensitive, right? Well then, I'd like to see which one's the more superior weapon—her tears or my fists!

When I was discharged from the psychiatric hospital, my brother and sister-in-law dropped everything to personally pick me up. Even my nephew, who had just finished his college entrance exams, arrived with a box of carrot cake he had waited in line all day to buy. His warm smile was the picture of innocence. “Auntie, congratulations on your discharge. With me here, you’ll never feel lonely again.” To outsiders, we were the perfect family—envied by all and even awarded the title of a local model family. But behind the facade of family bliss lay a very different story. On the very day my brother transferred the last of the family properties to me, I went live on social media. In front of an audience that idolized my so-called perfect family, I boasted about my "accomplishments." I conned my nephew into paying for a spot at an elite school, duped my sister-in-law into stepping into a scandalous club, and tricked my brother into losing everything he had worked for. “My brother has treated me with nothing but kindness. And I can only repay his kindness with betrayal.”

I return to the country after attending an international anesthesia academic conference. That's when I see the news of my boyfriend and twin sister getting married. I'm anxious to verify its authenticity, but my sister drugs me and induces me. "A substitute's child will only be an unwelcome bastard even if it's born. I'm just helping it move on to a better life." Then, she slices me open with a scalpel. She gouges my womb out, causing me to die from significant blood loss. Meanwhile, my boyfriend believes her lies. He's sure he's not the father of my child. He ignores my messages begging him to save me. Instead, he spreads the word about me eloping with someone else. He even wipes all traces of me from his life. "I will never see her again, forever and ever." Five years later, surveillance footage of my sister cruelly murdering me surfaces.

My older sister, Noelle Brown, has an unhealthy obsession with me. When I was ten years old, Noelle almost got kidnapped by the kidnappers. I got into the kidnappers' van in her stead. Later on, I was returned to my family after they paid a ransom. But my face had already been slashed by the kidnappers, and my legs had been broken by them, too. Since then, Noelle has worked extremely hard to improve herself. That's how she successfully brings the company Dad has left behind to a new level of success. I become Noelle's most cherished person as well as the vulnerable spot that no one else is allowed to touch. Someone made fun of my ugly looks in the past. Noelle had stuffed his head into a sack filled with rats, where he literally got his face chewed off him alive. There was also someone who ran his mouth about me being a cripple behind my back. Noelle responded by crushing his legs with a road roller, resulting in his legs being reduced to paste. Noelle is the demoness who's feared by the entire city. But to think that such a fearsome woman dotes on me endlessly. She even dumps a huge amount of money into sending me overseas, where I undergo numerous plastic and orthopedic surgeries while finishing my college studies. Before returning to the country, I receive an engagement invitation from Noelle. She tells me that soon, I'll have a brother-in-law who will spoil me like she does. She even sends me a photo of her fiance, Faris Smith. But as soon as I arrive at the villa, Faris barges in with a group of brutes. He's mistaken me for Noelle's side piece, whom she keeps in another country, so he begins torturing me endlessly. By the time Noelle reaches the scene, Faris points at me while shouting at her. "Don't tell me I can't even compare to that pretty boy!" Noelle's eyes go bloodshot at the sight. "What makes you think you're even worthy of being compared to him?"

My older sister was always kind-hearted, while I was born a natural troublemaker. When the intense heatwave struck, our family stocked up on supplies and stayed indoors. My sister saw a little boy, who seemed about seven or eight years old, crying and asking for help. She decided to take him in. “We’ve plenty of supplies anyway. One more person won’t make much difference. Besides, he’s just a child.” I warned her that the boy looked oddly mature and might not be as innocent as he seemed. I suggested we observe him a bit longer. She said I was a cold-hearted troublemaker by nature. Then, she went and let him in anyway. Not just that, but she also convinced our mother to force me to share a room with the boy. That night, the scheming “little boy” secretly climbed into my bed. I was brutally assaulted. Yet my sister told me to let bygones be bygones and marry him. To force me to obey, she locked me out on the balcony at over 140 °F. Enraged, I set a fire and killed everyone. When I opened my eyes again and saw my sister safe and unharmed, I smiled. This time, I would show them what a troublemaker really was.

My brother Mitchell sided with his dream girl when she accused me of bullying her. Despite being the only family member I had left, he exploded in anger and sent me away to a boarding school for so-called reformation to learn how to become a meek and obedient little sister. In time, I became exactly what he wanted—a docile sibling who never fought back, never argued. But everything changed the day he saw my medical report. He lost his mind. "Nora, I'm begging you—forgive me and let me be your brother again!"
