Demon

The human heart is always filled with various desires, leading to all kinds of grievances and enmities due to unfulfilled wishes. In this world, there exists a group of supernatural beings that enter into contracts with humans, fulfilling their wishes while exacting a strange price in return

The cat demon Ye Tong and the dog demon William, one is a contradictory cat who speaks insincerely, while the other is a loyal, gentle, and infatuated dog. One speaks harshly, enjoys fighting, and has a strong disdain for humans and dogs; the other is loyal and upright, resilient, and obedient to Ye Tong's words. As they interact with humans, they create various amusing stories, and amidst their playful banter and quarrels, they discover the true feelings from their past lives
