The King: Eternal Monarch

Lee Gon mourns the tragic death of his father. Lee Lim goes on the run — and finds escape when he comes across a door to a parallel universe.

Gon insists he is an emperor from another world. An incredulous Jeong Tae-eul takes him to the police station, where he sees a familiar face.

Though Tae-eul finds Gon's story difficult to believe, some things about him are completely inexplicable. At work, she gets busy with a murder case.

When Tae-eul loses her police badge, she can't help but think about Gon. Meanwhile, Kang Sin-jae has had it with his mother's bad habits.

Being introduced to Gon's world is a lot to process for Tae-eul, who's taken to the palace. A disgruntled Jo Yeong keeps an eye on her.

A potential military conflict threatens the kingdom. Gon promises Tae-eul he will return to her, and steps forward to take care of the situation.
