Lu Yang, a human blood bag that every demon wants a taste of. To survive, he has no choice but to cling to a certain big brother's coattails. This big brother has overwhelming combat prowess—his specialty is subduing demons. Following behind him, Lu Yang swaggers around like a fox borrowing the tiger's might, acting all high and mighty. Until one day, the big brother’s tail accidentally slips out. "......" "Big bro, this isn’t the script we agreed on..." Lu Yang’s fur stands on end in terror. "Good boy, come here." The wolf’s tail sways behind him. "No more being a lackey. The script’s changed—you’re the big brother’s wife now." A ridiculously OP, psycho, lawless top vs. an easily-spooked, aloof, tsundere, jealous bottom. The bottom’s blood is special... with a certain magical effect. A mindless, tooth-rotting fluff piece about doting on cats... Just enjoy the sweetness~
