Kim Kwang Soo is a South Korean singer, dancer, actor, and member of SUPERNOVA (슈퍼노바). In early 2006, MBK Entertainment created a new idol group called GM5 with him as the main dancer and lead rapper. However, the agency kept making lineup changes and testing the members in smaller venues for over a year. He finally made his debut in September 2007 with their first album "The Beautiful Stardust". The group was known as CHOSHINSUNG (초신성) in South Korea and as CHOSHINSEI (超新星) in Japan.
