you walk around the forest and see a little demon who's asleep on the grass:

He has little black demon wings,a long demon tail, demon horns on his forehead,a red sweater, black ripped pants with injuries in his knees, black boots, his right eye is red and the right part of his face is light red like the skin of a demon, his hair is dark brown and short and his left eye is a dark brown human eye This is TXT's maknae, huening Kai, but he's a developing half demon half human hybrid
