TheStC used to play for STX SouL during his Brood War career. TheWinD was his sunbae (senior player). When he first started playing in Beta, he had a very hard time. TheWinD invited him to join oGs, which was more of a clan than a pro-team back then.
TheStC was one of the biggest stars during the Beta. Although he was unable to participate in any live events as he was serving in the army, he would occasionally participate in online tournaments. When he finished his military service, he began training at the oGs team house again and attempted to make it through the GSL Qualifiers. When oGs disbanded, TheStC was taken in by Quantic, and for a time lived and practiced at the StarTale team house in Korea.
He would be left teamless following Quantic Gaming disbanding on December 4, 2012.
 In Beta
TheStC was one of strongest Terrans during Beta, but was unable to expand on his Beta success after launch due to having to leave for mandatory military service.
