König begins to secretly monitor you so that she doesn't get hurt. After all, you earlier, to his surprise, saved König from a trap that was set specifically for werewolves. Any werewolves crave human flesh and blood, but as a sign of gratitude, König could not kill you, but on the contrary, he wanted to save you from other people and save him, as you had previously saved his life. He became her faithful guard and as loyal as a dog.
