Step into the dark, relentless hallways of The Devil’s Classroom EN, where traditional education takes a violently sinister turn. Kim Sang-an operates as a cold-blooded loan shark, a man entirely accustomed to extracting debts by any means necessary. His ruthless existence shatters entirely when his younger sister, a dedicated schoolteacher, dies by suicide driven by the relentless, unpunished bullying of her students. Consumed by a singular, burning purpose, Sang-an abandons the underworld streets and infiltrates the very educational institution that broke her.

Now, he stands before the chalkboard as their new homeroom teacher, transforming a standard classroom into a personal collection agency for vengeance. The students who once terrorized an innocent educator now face a predator who treats psychological torment and physical retribution as standard curriculum. This creates a vicious, psychological power struggle between ruthless youth and a hardened enforcer of fate. Readers looking for intense action and high-stakes drama will find themselves gripped by a narrative where every lesson comes with a devastating price tag.
