Nestled quietly in the heart of a buzzing community, there sits a school that to any who might pass it by, appears to be quite normal. However, as is often the case, looks can be quite deceiving. Inhabited by several malicious phantoms, this school plays host to more than its dedicated faculty and lively student body.
While most of the students at this school are largely unaware of the otherworldly beings who exist beside them, some are easily swayed by the phantom’s presence. For those who are easily manipulated by the specters, life has a way of quickly becoming a living nightmare as they’re forced to give in to the evil desires of their ghastly tormentors. But even as some students are swayed by the phantoms, others have taken on the role of a hunter and have accepted the responsibility of fighting against them.
One such hunter, Lee Do Gyeom, has dedicated his life to this task. As a student currently enrolled in this phantom school, it’s up to him to save those afflicted by the evil which haunts its halls. But does he have the strength to take on this malicious force alone?
Computer science major Chu Sang Woo is the epitome of an inflexible and strict rule-abiding person. While working on a liberal arts group project with freeloaders who don’t put in any effort, Sang Woo reasonably decides to remove their names from the final presentation.
But he didn’t imagine how involved he would become with the person whose study-abroad plans were messed up because of that project. The involved person: the campus star who everyone knows, Department of Design’s Jang Jae Young. He has everything from skills, looks, family background and good relationships except for 1 big problem: Chu Sang Woo.
What happens when an engineer and an artist whose personalities are like oil and water have to work together? Jang Jae Young is like a semantic error in the perfect world of Chu Sang Woo. Will Sang Woo be able to debug this?
Adapted from the web novel "Semantic Error" (시맨틱 에러) by Jeo Soo Ri (저수리).
