I Turned Down the Campus Beauty, and Now a Yandere Demoness Won't Leave Me Alone

[Redemption] + [A Yandere Who Grows Over Time] + [Sweet, Naive Hero vs. A Heroine Who Says One Thing but Means Another] + [Single Heroine] + [Book Transmigration] Lu Xiao transmigrates into a brainless male power fantasy where the protagonist gets abused, becoming a backup love interest. According to the original plot, tonight he’ll kneel in the plaza and confess to the campus belle, only to have her publicly humiliate him. Screw the campus belle! I’m done being a doormat! Just as he thinks he can escape the damn plot’s vortex, he finds a girl covered in blood in a deserted alley outside the campus. Shen Zhiyue, the ultimate dark villainess in the original story: a ruthless killer who, later on, drags the Dragon King protagonist to his death alongside her. Looking at this trembling, not-yet-fully-grown young yandere, Lu Xiao grits his teeth, scoops her up in his arms, and carries her home. “Don’t get involved. Let me die.” The girl’s eyes are lifeless. “Like hell you will! I spent tens of thousands on your medical bills. Your life belongs to me now!” Lu Xiao shouts irritably. He only wanted to steal the Dragon King protagonist’s most powerful cheat, but can someone tell him why this little girl, whom he’s been force-feeding and buying new clothes for, looks more and more unsettling by the day? “Lu Xiao, you looked at that receptionist for a second too long today.” Shen Zhiyue clutches the fruit knife in her hand, but wears a lovely smile. “If you ever stop wanting me… I’ll kill you first, then kill myself.” Lu Xiao looks at Shen Zhiyue, who is handing him warm water from beside the sofa while saying something so shocking, and feels his scalp go numb. Wait, is something wrong with this script? I only wanted to live a quiet, safe life in the city. How did I end up becoming the only one who can save this yandere as she grows up?
