Seon-ji, een charmante aspirant-patissier, heeft een geheim dat zelfs zijzelf niet kent: ze is vervloekt en verandert elke nacht in een onhandelbare duivelin. Overdag heeft ze geen herinnering aan de nachtelijke Seon-ji en haar onbeschofte gedrag. Haar familie neemt de onhandige en werkloze buurman Gil-gu in dienst om 's nachts op haar te passen. Terwijl hij smoorverliefd wordt op de middag-versie van Seon-ji, besluit Gil-gu om de vloek te ontrafelen en beide versies van het meisje te helpen hun eigen toekomst te vinden.
