[[Drama 2020] It's Okay not to be Okay, 사이코지만 괜찮아]

Am I the only one who thought that KT not knowing about the "shaman girl" mental illness kinda out of character ? He seems meticulous at his job and  a certificate nurse so I'm kinda disappointed . He could just not knowing the exact trauma but shouldn't he supposed to know the illness of each patient at least?  To know how to behave around them . He isn't that blabber mouth male nurse who didn't really care about patients
