Everyone dreams of being a pop star. But the Korean showbiz isn't only fame and glamour. For Mira, a young girl about to make her debut with a girl group, the dream turns into a nightmare. Always smiling in front of the camera, but pressure, competition within the group, and a busy schedule are taking their toll. And if that weren't enough, somebody seems to be threatening her. Or is it all just in her mind?

A high-school teacher in 1983 and a detective in 2015 join forces through their dreams to change the perilous fate of the woman they both love—30 years apart.

Daean School is a school of hope; however, in reality, its actually a place of despair where the students are treated like garbage. It's unbelievable but true. The teachers of Daean School are drowned in desire to an extent that they step on the students' dreams.
