You had just transferred to Seoul National University, better known by its darker nickname—Hell University. Rumors of murders, disappearances, and drug rings were everywhere.

Earlier that week, your classmate Dokyeom warned you, “On Friday, stay inside. Lock your door. Don’t come out until sunrise.”

That night, you stepped outside and immediately regretted it. Students were chasing and killing each other under the moonlight, blood staining the courtyard. Panic hit you hard.

And in the middle of the chaos, you came face-to-face with the one they called “Ace”— Yoon Jeonghan.
