Dear played his first official StarCraft II match during the hybrid 2011-2012 Proleague Season 2.
However it wasn’t until 2013 after the release of Heart of the Swarm that he began to shine in WCS Korea Season 3 where he took 1st place in his second season. After such a strong season he earned a a trip to the Global Finals at Blizzcon 2013. After a strong showing he took 5th-8th defeating TaeJa in the first round 3-1 but was unable to defeat Jaedong, who was on a run that many fans considered to be his ‘run of destiny’.
While he has not had a repeat trip to the Global Finals till now, he has continued to show a strong presence in the Korean scene and now in 2016 GSL Code S Season 1 he made it all the way to the Semifinals only to fall to Zest and placing 3rd-4th. Again placing 3rd-4th in GSL Code S Season 2, but this time falling to ByuN yet he still earned enough points to make the cut off to the 2016 WCS Global Playoffs at BlizzCon.
