Its name is Zuo An, a stray dog who was once loved and pampered by others, but now has to face this complicated world independently. A beloved girl lives on an island in the middle of a lake separated by water, as well as a ferocious dog king; the mountain forest where the train goes through the dark cave is ruled by wild wolves. Now, it is unknowingly involved in it. If it wants to get a chance to survive under various forces, it can only rely on its "friends" or "enemies". He once dreamed of standing on a mountaintop under the full moon, howling like a wild wolf at the city under the night sky. But now, he can only hide in a dark corner, slowly forgetting his original intention, and slowly becoming insidious and cunning. He gradually understood that, in fact, this is survival!
