In the Age of Dharma Ending, Li Chenglin is the sole monster-catcher left in the entire world. He originally hoped to make a living relying on this trade, but monsters kept piling up, and his home became more and more crowded—Ailiya the vampire constantly eyes his blood, Chen Yaoyao the ghost bride acts aloof by day but always drifts into his room at night, and there is also Lu Wangshi, the dutiful little zombie who works hard to cook congee and buy fried dough sticks. To support this household of demons and monsters, Li Chenglin leads them to work, living a life that is chaotic yet full of vibrant warmth. The vampire and the ghost bride vie for his affection out of jealousy, while the little zombie handles the finishing blows. In a rental apartment within this city, humans and monsters crowd together, turning everyday life into the most bustling human warmth.
