Under the city of Luoyang in the Tang Dynasty, there were spirits of cats who roamed night over night, stole people's skin bags, invited them to dance together, and empathized with them. In the dance studio, when the noble young master meets his childhood dream lover again, is what he is intoxicated with? Is it the familiar skin bag, or the fiery heart of the century old cat under the skin bag? In the clan manor, the black cat severed its tail and sought the rebirth of its former benefactor. Did she wait for the love of her life, or was it a vortex intertwined with desire and betrayal? In the ditch, the mouse spirit fell in love with the little cat demon. What he longed for was a self destruction towards happiness, or a love song that rewrote fate? A city, three cats, entwined with a thousand emotions and desires.
