Chaser was born on August 1, 1995 in Gyeonggi, South Korea. He started playing League of Legends in August 2012 with Ashe as his first champion.
Chaser played as a sub for Jin Air Green Wings Stealths in PANDORA.TV Champions Winter 2013-2014. However, the team failed to make it out of the group stage. Following the tournament, he was transferred to Jin Air Green Wings Falcons as starting jungler after ActScene left the team. The Falcons lost all their games at HOT6iX Champions Spring 2014 and fell during the group stage. In May 2014 he was switched back to the Stealths. This is when he decided to change his name from RealFoxy to Chaser. The Stealths made it out of groups at HOT6iX Champions Summer 2014 but lost to Samsung Blue (3-0) in the quarterfinals.
Due to the changes in OGN, the Falcons and the Stealths were forced to merge to create the Jin Air Green Wings. He was meant to share the starting jungle spot with Winged but Chaser ended up playing in almost all of the games of SBENU Champions Spring 2015 anyways. Jin Air qualified for the playoffs but faltered at the end of the season, losing 3-0 to CJ Entus and ultimately placing 4th. Jin Air then attended SBENU Champions Summer 2015 but placed 6th overall, gaining 10 circuit points and qualifying for the next season of LCK but barely missing playoffs. Jin Air was seeded into the first round of the 2015 Season Korea Regional Finals and made it all the way to the finals but they lost 3-1 to KT Rolster.
Chaser left the organization in 2015 to join Longzhu Gaming (former Incredible Miracle) for the 2016 Season together with teammate Cpt Jack. There were high expectations from the team and its 10-man roster, as it include Flame, Expession and Coco. However, the team did not even make it to the playoffs in both Spring (7th) and Summer (8th). In the 2016 LoL KeSPA Cup, they finished 9-14th after losing to Jin Air Green Wings (1-2).
On November 30th, Longzhu Gaming announced the departure of Chaser from the team, along with some of his teammates. On December 15th, Team Dignitas announced that they signed Chaser as the team's starting Jungler for the 2016 Season where he will be playing alongside KT Rolster's former Top laner Ssumday.
