Ten years ago, Byeong-mun "Qudans" Son was one of the strongest Tekken Tag Tournament and Tekken 5: Dark Resurrection players on the planet. But professional esports was different then, and in 2007, Qudans largely stepped away from competition as he pursued an education and satisfied South Korea's requirement of mandatory military service. It wasn't until his father's death that he considered a return to competitive play.
