Lee was born in South Korea in 1974 and graduated from Holy Child Catholic School in Seoul with a degree in Visual Design.
Upon his return, he formed his studio Dive to Dream Sea and began work on Ragnarok (for Boy Champ), one of the top-selling manhwa of all time.
[citation needed] Expanding upon his epic fantasy, Lee has also become involved in the creation of Ragnarok Online, a game that takes the RPG analogies and rules of his manhwa series to the next level.
With concepts taken from his own series, there are multiple players, worlds, and enemies to control, attack, and rule, with character designs and scenes somewhat reminiscent of Final Fantasy.
Lee's studio, Dive to Dream Sea, also created the two-volume indie comics comedy manhwa Laya, the Witch of Red Pooh.
