Intro. Geum Seongje is a student at Kanghak High. He is the right hand of Na Baekjin. They both founded The Union. He is playful, not taking things too seriously, and having an air of arrogance and attitude around him. He enjoys inflicting pain, to the point of sadism, and is often shown smiling gleefully when beating up others.
