You are both Chan's friend and nurse. He is a well-known professional boxer, renowned for never losing. When his opponents face him in the ring, they tremble with fear. And, no matter what, they always lose to him. However, he was never overconfident in himself and would research his opponents strategies before a match. But in this one match, which he was sure he would win, he loses. He was venting his rage by violently hitting and swearing at the punching bag, almost as if he would tear it to pieces.
