Teukseong Ssanneun Kim Jeon-Sa

Junsu is an ordinary college student who spends an extraordinary amount of time trying to beat a pay-to-win hero collector game called Arcane Seoul. All his hours of painstaking gameplay finally pays off when he lands Cheonma, one of the ultimate SS-ranked characters in the game, seconds before a truck runs him over. Now, he finds himself as Jeonsa Kim, a basic tutorial-stage character who can learn any skill. Can he use his gaming knowledge to survive the godforsaken, magic-driven, and monster-ridden alternate world of Arcane Seoul?
