Why Does The Sister Kill In 'My Sister Killed Me With Kindness'?

My adopted Omega sister, Maya Bardolph, is known to be innocent and kindhearted. Before the practical admission assessment, I specifically tell her not to interfere in any way. But she secretly puts a prohibited performance booster into my water bottle. I am reported for cheating on the spot. My results are canceled, and I am permanently blacklisted. When I break down and demand an explanation, she bursts into tears, looking pitiful and wronged. She weeps, "Sierra, I just wanted you to get first place... I didn't know things would turn out like this." My boyfriend, Dale Ashshade, immediately pulls her into his arms and blames me instead. He scolds, "She is only trying to help. Why are you being so harsh to her?" My parents chastise me frostily as well. "Isn't it just one practical assessment? She's an Omega. She doesn't understand these things. Can't you be more patient with her?" To apologize, Maya smilingly brings me a cup of herbal tea later. "Sierra, I made this just for you. Promise you won't be mad at me anymore after you drink it, okay?" Without thinking much about it, I drink the tea. But what she uses to brew the tea is highly poisonous silver oleander. I die from the poisoning. Outside the emergency room, Maya cries hysterically, "I'm sorry! I didn't know silver oleander is poisonous... I just wanted to apologize to Sierra..." When questioned by the Enforcers, Dale calmly gives false testimony. "After Sierra was caught cheating, she became mentally unstable. She couldn't accept how things turned out and took silver oleander to kill herself..." When I open my eyes again, I return to the day before the assessment.

My name is Adrian Hart. The day my sister Serena found me and brought me home, I thought I finally had a family again. I was wrong. In Serena's eyes, her adopted brother Evan mattered more than I ever would. When he was too scared to marry into a powerful family, I walked down the aisle for him. When he wanted out, I swallowed a fake-death pill and disappeared. Every time, Serena swore it was the last. The seventh time, she poured the pill down my throat herself. And that was the time I actually died. My soul stayed behind. I watched Serena stand over my body in the morgue and fail to recognize me until it was too late. And the cruelest part wasn't dying. It was knowing that, until my very last breath, my sister still wasn't on my side.

My sister, Yvonne Jones, tried to murder the childhood friend of a rich heir in order to seduce him. Yvonne poisoned the woman's drink and pulled out her oxygen tube after she was sent to the hospital. When the rich heir arrived in a rush, Yvonne cried in his arms daintily. "I'm so sorry. This is all my fault. I failed to protect her." I witnessed everything in the ward but didn't say a word about it. In my previous lifetime, I stopped Yvonne from poisoning the woman. I knew the rich heir would never let her get away with it if he found out about it. Yvonne was forced to give up her plan and even praised me for my foresight. However, she ended up poisoning me instead and stabbed me in the heart with her dagger when I got dizzy. "This is your fault! Die! If you hadn't stopped me, Sean Graham would've been mine!" When I opened my eyes next, I had returned to the day of the poisoning.

My brother was a twisted, paranoid psychopath. When I was ten, my parents were murdered. Both my legs broke off while I tried to save my brother. I became his only family and also Achilles’ heel. Those who mocked me as a crippled would have their bones broken, and anyone who tried to hurt me would be smashed into a pulp. As he reclaimed our family’s fortune, he became “the Devil” in Amberwater, a man no one dared to offend. Yet, he alone spoiled me like I was a little princess. Everyone knew that Lucas’s sister was untouchable. He had sent me abroad to receive the best treatment. The day that I could finally stand up again, I received an invitation to my brother’s engagement banquet. “Veronica, we’re going to have a new family member soon.” I heard that his fiancee was the daughter of a wealthy family. She was gentle and virtuous. I dressed beautifully to meet her and planned to give her the jade bracelet that my mother had left behind. However, she had me kidnapped and taken to an abandoned construction building. “You lowly little witch. I’ll rip that face of yours since you’re such a seductress. I’ll see how you’ll steal my man now!” She crushed my mother’s heirloom, broke all my limbs, and ripped my face off. Then, she ordered a dozen men to torment me to death. In the end, she stuffed me into a gift box and sent it to my brother. “Dearest, this is your wedding gift. Do you like it?”

My older sister, Holly Keller, is studying in the public library for her SATs when a stray bullet hits her. Blood pours from the wound. Instead of stopping, I quicken my pace, walking right past her and acting like I haven't seen a thing. It was because, in my past life, I took her to the hospital as soon as the accident happened. The gunshot to her head caused severe intracranial bleeding, and she needed surgery right away. I called our mom, who happened to be the top neurosurgeon in the city. And I begged her to get to the hospital as fast as possible. But she assumed I'm just being jealous because she had taken my adopted brother on a trip instead of spending time with me. Assuming that I was making the whole thing up to ruin their trip, she flat-out refused to come back. By the time Dad and the rest of the family arrived at the hospital, Holly was already gone despite the doctors' best efforts. The entire family blamed me for Holly's death. They believed I had deliberately misled Mom just to screw up Holly's chances of getting treated in time. When Mom finally rushed back from out of town, she completely lost it. She shoved me down the stairs and watched as I bleed to death. When I open my eyes again, I'm back to the day Holly is shot in the library.

At the age when I should have been attending university, I was framed by my biological parents and sent to prison. My sister had been cruelly killed by her kidnappers when she tried to save me, and they blamed me for her death. On the day of my release, I was kidnapped and had one of my ears cut off. When I found the opportunity, I immediately called my father, asking him to save me. Instead, he snapped, saying, “You’re no longer my son! Don’t contact me!” I was then burned alive. After I died, my sister returned. However, when my parents found out that the charred corpse was mine, the family crumbled.
