He retired from professional play following an injury. During his tenure on Team SoloMid as a support player, Lustboy won the 2014 Summer and 2015 Spring NA LCS.
"I really like to make innovation...I like trying new things no one's ever tried before. But already made SC1 a long time ago so there ."
He later turned semi-pro playing Starcraft II, joining the Korean Team Prime as a substitute in 2010.
MiG Blaze
The next year he began playing League of Legends with a number of soon-to-be professionals. One of these, Dong-jin "Helios" Shin, would later sign as an AD carry with Maximum Impact Gaming Blaze, and then bring on Lustboy as support when the position became vacant. As part of MiG Blaze, Lustboy took first place at the first OnGameNet tournament at Champions Spring 2012, winning the largest prize pool in League of Legends history up to that point. That same year, they became the first Korean team to compete professionally in North America at Major League Gaming's first arena tournament, winning the competition with 10 wins and one loss. MiG was acquired in 2013 by CJ Entus, and the now newly dubbed CJ Entus Blaze, went on to place first in the World Cyber Games 2013 Korean qualifiers. Lustboy left Blaze in 2014.
Team SoloMid
Lustboy joined Team SoloMid of the North American League of Legends Championship Series in July 2014, replacing former support, Gleeb. Lustboy described TSM as "like a dream team". Prior to the official announcement, TSM owner Andy Dinh was fined $2,000 for announcing the acquisition of Lustboy before receiving League approval for the transfer. Along with Lustboy, TSM finished as the top North American team of 2014, with Lustboy ending with a 2.73 KDA. In the world championship that year, they were eliminated in the quarter-finals to future world champs Samsung White, but were the first team to take a game off them which was matched by Star Horn Royal Club in the finals. 2015 Worlds was no better as they placed 4th in Group D, following their disappointing performance at the world championship TSM announced that Lustboy was retiring as a player for the team. Described as "arguably the best support in the NA LCS," at the time he ranked fifth among North American supports in KDA at 3.65, and fourth in gold-per-minute at 227. He continued as a streamer for TSM, and as an analyst for the team where he was centrally involved in the process of creating a new roster following the simultaneous departure of teammates Lucas ‘Santorin’ Larsen and Marcus 'Dyrus' Hill. He left the team on July 11 and was replaced as support by YellowStar. In TSM's official announcement, Lustboy is quoted as saying:
"Due to shoulder injuries and being tired of playing, I decided to step down as a player but I’ll still be involved with TSM helping in anyway possible. I will never forget how much fans and everyone treated me kindly, and I appreciate the opportunity given to me by TSM to prove my skills even though I was a foreigner."
