While in hot pursuit of wanted criminals, a police officer has an unexpected encounter with a rather uncanny demon. Barely surviving the accident, Do Gyeong Joon is left baffled, staring at the sky at the retreating form of the mysterious man he had just met. However, not long after, the two meet again when the demon crashes into Do Gyeong Joon’s apartment, whispering:
“Hurry up! You need to get inside me-”

Jung Intae may be the first to admit he’s a psychopath to the school nurse (his crush), but he certainly isn’t the last. Consequently, Miss Kim’s been dealing with a lot of high school psychopaths... Not that any of them really fit the bill. But dig a little deeper and it seems like everyone at the school, including the faculty, is harboring a secret... Like Intae’s obsession with Miss Kim, and the anxiety Miss Kim seems overwhelmed by at times. Someone at the school really is a psychopath, but who?
