I Accidentally Became the Demon World's Sister-in-Law

Lu Yang is a walking blood bag, the kind every monster wants to take a sip from. To stay alive, he has no choice but to cling to a powerful big brother. Big Brother is absurdly strong and makes a living hunting demons. Lu Yang follows behind him, throwing his weight around like a fox backed by a tiger. He's never been more arrogant. Until one day, the tail behind Big Brother slipped out by accident. "..." "Big Brother, this isn't how the script was supposed to go..." Lu Yang's fur stood on end in terror. "Good boy, come here." His wolf tail swished behind him. "Forget being my underling. The script's changed. You're going to be my wife." A ridiculously powerful, unhinged, shameless top vs. a prickly little cat: a cool, tsundere bottom who's a jealous little thing. The bottom's blood is special... It has a magical effect. A mindless, sweet story about pampering a cat... I just hope you have fun reading it... Cover art thanks to Daming~ Theme:
