Prom, a member of K-Pop group Destiny, has a secret. In his past life, he was Prometheus, cursed by Zeus for eternity to fear fire. This curse keeps messing with him—he can't even blow out birthday candles! But one day he meets Sora, a college student, at a fan signing and recognizes her as Pandora! He knows Pandora's box can save him, but she has no clue what he's talking about. With his acting debut as a fireman at stake, will Sora remember who she is and extinguish Prom's fears for good?
