Knee started playing Tekken with the first iteration of the series, when he was in elementary school. While growing up he continued to hone his skills, spending much of his free time playing Tekken at different Korean arcades.
By prioritizing fun over being a specialist, Knee developed a vast character knowledge over the years, eventually becoming known for utilizing all kinds of characters in high level play. Throughout his career he has shown full mastery over a plenitude of characters, such as Bryan, Devil Jin, Dragunov, Bruce, Paul, Steve, Hwoarang, Kazuya, Miguel, Jin, Heihachi, Shaheen, Josie and Lili. Knee is considered by many to be the greatest Tekken player of all time.
In the Tekken World Tour Knee had a relatively sombre first season in 2017, only winning a Challenger event at Abuget Cup and in a shock upset, lost all of his Group Stage games at the Finals, with losses to Nobi, Saint and Jimmyjtran. However the 2018 season would be a complete return to form for the Korean, winning a grand total of five Master events en route to the Finals once again, eventually finishing 3rd overall after being eliminated by eventual winner Rangchu.
