Yu Lishan has been a dominant figure in the Taekwondo Club for so long that he no longer knows his own limits.
In fact, he believes that becoming the president is simply natural, and everyone must listen to him; this is necessary.
However, his arrogance and bullheadedness have been destroying him, leading him to constantly make mistakes.
When a person's heart becomes twisted, no one can save them; only when they come to a realization can change happen.
Yu Lishan has completely forgotten the original camaraderie; now, all he remembers is their abandonment. He feels particularly pathetic, as if he's been used up and discarded like a worn-out rag with no value.
