Kim Go-eun portrays Detective Jeong Tae-eul from the other universe which is similar to present-day Korea.

Why are We Seeing Parallel Worlds?

25 years ago, Lee Gon’s power-hungry uncle Lee Lim killed Lee Gon’s father because Lee Lim desired ownership of a magical flute.


8-year-old Lee Gon discovered his dying father and ended up cutting the flute in half while protecting himself.


A mysterious figure saves young Lee Gon, but Lee Lim escapes with one half of the magical flute and discovers the parallel universe. The mysterious savior leaves behind Jeong Tae-eul’s detective badge from 2019.

Fast Forward 25 Years

Lee Gon is all grown up (super handsomely) and discovers the portal to the parallel universe with his half of the magical flute. He realizes the worlds are very different and there are doppelgängers with different lives in each world.
