Jason "JaeYoong" Yoong (sometimes referred to JaeYoongJo) looked to follow in the footsteps of his brother, a professional e-sports player in Taiwan, from an early age. He played games such as Heroes of Newerth and StarCraft 2 before finally picking up League of Legends.
He was offered to play in Korea as a professional StarCraft 2 player, but turned down the offer due to Hagane's invitation into the Malaysian national League of Legends team, Kuala Lumpur Hunters.
JaeYoong traveled to Bangkok in July 2013, ostensibly to visit the WCG 2013. However, during the event, JaeYoong joined Bangkok Titans. On October 17, 2013, JaeYoong returned to Kuala Lumpur Hunters as the AD carry.
