When a night out to a piano recital turns into a literal nightmare for Seo-Yun, she's unceremoniously inducted into a world of horrifying beings. There, she meets Hui-Won, a charming "superbia" who informs her that she is nothing more than food for these creatures born of sin. Now, she must succumb to the likes of vampires and incubi as they feed on her for sustenance. Can she escape the darkness that lurks under the cover of night, or will she find a reason to stay inside this sinister realm?
