Jia was dumped by her boyfriend for her inability to feel pleasure. While wandering drunk, she ends up in the health office of the school where she works. There, she runs into the school nurse, Kim Nak-won, famously nicknamed 'Nightingale.' In her drunken state, she confesses her secret: 'Sir... the truth is... I can't feel anything! Please, cure me!' To her surprise, Nak-won makes a suggestive proposal: 'Want to work overtime? With me?'
