"In a world of perfect logs, he is the only ghost in the machine."
Kang I-ro is a genius hacker who views the world in variables and vectors. His only goal? To live a quiet life, leaving zero traces in any system. But when the school's powerful elite, Gu Ja, deletes I-ro's sanctuary from the digital records, the silence is broken.
Instead of deleting Gu Ja back, I-ro chooses a more elegant revenge: The ㄱ (Giyeok) Algorithm. By warping spatial coordinates rather than erasing data, he redirects the system's power without leaving a single red flag.
But as a mysterious blackout looms over the campus and a familiar "knock" appears in the hacking packets, I-ro realizes he's not the only one watching. Between the philosophical teachings of a ghostly basement janitor and a looming external threat, I-ro must decide: will he remain background noise, or will he become the architect of a new reality?
Dive into a gripping techno-thriller where coding is a weapon, and the system is never what it seems.
