Turning My Junior Sister Into A Mary Sue In This Yuri World

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.

I failed my college entrance examination. My father decided to sell me to the village chief’s hot-tempered, crippled son. My younger twin sister helped me escape in the middle of the night. It was only later that I discovered my younger sister was the one who had failed the examination. She used my identity to attend college and hooked up with a rich heir. At her engagement banquet, they revealed the truth that she had taken my identity. As a result, the event fell apart. Out of rage, my sister pushed me down the stairs. I grabbed her and pulled her down with me. When I opened my eyes again, I returned to the day the examination results came out.

In my previous life, on the day my sister and I attended the Witch Covenant's mating ceremony, I saved a fallen vampire prince. To repay my debt, the prince, upon returning to his clan, immediately declared that I would be his future bride. A year later, I gave birth to a pureblood heir—the only successor of the entire vampire lineage. The prince was overjoyed. On the day of his coronation as King, he sealed a blood bond with me, declaring me his eternal companion and queen. From that moment, I was revered by all races. My sister, meanwhile, chose a powerful werewolf Alpha, only to fade into obscurity as one among his many lovers. Her jealousy of me spiraled into madness. During a full-moon ritual held by the witches, she pushed me into an abyss, leaving me to die from the fall. When I opened my eyes again, I saw her running toward the direction of the vampire prince's misfortune on the very day of the mating ceremony. I knew then: she, too, had been reborn. But what she didn't realize was this—becoming the prince's bride was easy. Winning his heart, bearing his child, now that was as impossible as climbing to the heavens.

The day I marry Navy Captain Dean Aldridge, I hear his stepsister Shirley Pierce's inner voice. "Diane is so beautiful and graceful. I wish I could be like her, but I'm nothing more than an unwanted burden in this family… "I really adore her, though. I saved up my allowance to buy her a bracelet as a wedding gift, but I'm afraid she'll think it's unlucky and refuse it." In my last life, those words had filled my heart with pity. I'd accepted the bracelet and even taken Shirley under my wing, teaching her to read and write. But not long after my wedding, my health began to deteriorate for no reason. It wasn't until I lay dying that I discovered the truth—the bracelet Shirley had given me was cursed, and she'd deliberately made me hear her inner voice. She'd long been in love with Dean and was determined to make the Aldridge family hers one day. Now, when I open my eyes again, I find myself back on my wedding day.

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!"

My roommate was obsessed with those cheesy “milk-scented girl” romance stories. She wanted to become the kind of heroine from those books. Tiny, soft, and delicate, the type who was supposedly so sweet that even her farts smelled like milk. So she went completely overboard. She lived on dairy. Drank milk nonstop. Even took milk baths. She tried everything, all because she was convinced she’d eventually run into her destined male lead. I believed in letting people make their own choices. What I didn’t expect was for her to go after my boyfriend, the guy I’d basically grown up with. One day, she sent him a carefully posed thirst trap. He replied with one word. “Get lost.” Then she proudly showed me the screenshot, like she’d won something. “Only girls like me, soft and sweet and irresistible, deserve a powerful man’s obsessive love.” “Don’t be fooled by how cold he is now. He’ll be crazy about me soon enough. He’ll want me all to himself.” I was just about to tear into her when a row of floating comments suddenly appeared in front of my eyes. “Fresh one, guys. This host is bold. Coming in with a thirst trap right away? Nice.” “Wait, what? Isn’t this just harassment? The male lead already has a girlfriend.” “Bro, I think you’re in the wrong livestream.”
