She Pretends to Be Sweet and Teases Her, but the Brooding Beauty Falls for Her

[Quick transmigration + Romantic Tension + Love Rival Showdowns + Sweet on the Outside, Dark Within + Obsessively Devoted Yandere] Ruan Shengsheng spent hundreds of worlds as a background character. At last, it was her turn to win over the male lead. But as soon as she made her move, she discovered that the original heroine had been reborn: She wasn't after the male lead. She was after the gloomy beauty at Ruan Shengsheng's side. And that beauty was gazing at Ruan Shengsheng with the gentlest eyes, like a dog ready to bite out someone else's throat at any moment. World One: Servant Siblings vs. the Brutal Demon Lord The Demon Lord's chains encircled Ruan Shengsheng's neck. She gave them a light tug, and the monster who killed without batting an eye bowed his head and obeyed. But in the corner, her brother slowly wiped the blood from his fingertips, smiling harmlessly. "Shengsheng, don't play for too long." World Two: Bankrupt Uncle and Nephew vs. the Arrogant Young Master The capital's pampered young master was foul-tempered and unruly, yet he knelt before her with red-rimmed eyes and asked, "Who are you going to choose?" Before she could answer, the young uncle behind her had already wrapped an arm around her waist and said gently, "Of course Shengsheng will choose me. After all, we're the closest to each other." World Three: Contract Marriage vs. the Cold Emperor Emperor Shen Wenzhuo took her as his consort, but on her wedding night, someone pulled her into their arms. Her nominal husband kissed her earlobe, his gaze taunting. "Your Majesty, did you ask for my opinion before taking my wife?" The System thought Ruan Shengsheng was dutifully winning over the male lead, unaware that In the surveillance footage, the gloomy beauty's eyes remained fixed on her, his smile growing feverish: "Shengsheng, I really can't live without you."
