Gray (voiced by JB Blanc) is a wolf who is handsome and arrogant, dreaming of becoming the leader of the wolf pack. Old Ji is Gray's formidable rival, competing with him for the position of wolf king, and they decide to settle their rivalry through a contest. The night before the contest, Gray accidentally falls under a spell and transforms into a sheep. He has to leave the wolf pack and live with the sheep. Old Ji takes advantage of the old wolf king's unawareness and pushes him off a cliff to seize the title of wolf king. A little lamb escapes to the northern pasture and is captured by the wolf pack, and Gray saves it. This act infuriates Old Ji, who decides to attack the sheep. When Gray learns that the wolf pack plans to attack the sheep, he decides to lead the sheep in defense against the wolves. While building the defense line, Gray is found out to have connections with the wolf pack, causing everyone to lose trust in him. He has to leave the sheep pack alone, and along the way, he encounters an opportunity to revert to being a wolf due to magic. However, upon learning that the wolf pack is about to attack the sheep, he gives up the chance to become a wolf again and resolutely returns to the sheep pack, leading them to defeat the wolf pack. Eventually, the two groups reach a peace agreement.
