my student cant be a psychopath

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?
