Why? Because everytime, we, the human get tired, the wolf will always take over to protect our body and vice versa. We tolerate and always be there with each other in order to protect our body together.
But right this moment, Rico feels empty in mind and in his heart, as he, the leader of the troop need to decide on which move he should make.
