Transmigrated As The Villainous Senior Sister

Bai XiaoXiao transmigrated into an unfinished novel — Because the heroine Xia WanMeng was breathtakingly beautiful, The original Bai XiaoXiao, consumed by jealousy, stirred up trouble again and again, driving Xia WanMeng step by step down the path of darkness.
This time she’s holding the script. Determined to fix her mistakes, Bai Xiaoxiao sets out to dote on the heroine instead: “Are you hungry, Junior Sister? Are you tired, Junior Sister?” She’ll pamper her, protect her, and spoil her until the heavens blush. But the more she fusses, the more she notices something off — why does her Junior Sister seem… different?
Xia WanMeng has been reborn, clutching a burning grudge. She swore to make Bai XiaoXiao taste the pain of her last life. Only — this Senior Sister is nothing like before. She’s clumsy, sweet, and impossibly earnest. And when Bai XiaoXiao starts flirting with the idea of finding a soulmate, Xia WanMeng loses it: “No way — Senior Sister is mine and mine alone.”
