Substitute Hero

In an effort to escape the impending danger posed by the Demon King, the inhabitants of an alternate world start summoning formidable warriors from various realms. Amidst this chaos, an unremarkable office worker named Song Lee-seok is inadvertently summoned simply due to sharing a name with South Korea's most powerful martial artist. However, the denizens of this new world mistakenly believe him to be the fabled hero! Thrust into a fabricated adventure, can this entirely average individual maintain the ruse and somehow vanquish the Demon King before his real identity is revealed?
