When dawn breaks, she becomes chilling. Escape from the devil’s curse!

After quitting his job, unemployed young man Gil-gu leads a dull, stay-at-home life until he falls head over heels for Seon-ji, who moves into the apartment downstairs. However, the next morning, he encounters Seon-ji in the elevator with a bizarre appearance, leaving him shocked and confused between the innocent Seon-ji and the eerie Seon-ji.

From that day on, Gil-gu hovers around her with half curiosity and half fear about Seon-ji’s true identity, until her father Jang-su reveals the family’s special secret. Seon-ji is gentle and ordinary during the day, but when dawn breaks, a devil awakens and she transforms into a completely different person.

Jang-su offers Gil-gu a perilous part-time job as Seon-ji’s protector only during the dawn hours.

Can Gil-gu escape from the curse of devil Seon-ji?
