Sezon 1

As a child, Nam Ji-a loses her parents. Two decades later, a curious case involving a runaway bride and a man with a red umbrella catches her attention.

Recognizing Lee Yeon as her childhood savior, Ji-a thinks he might have a lead in locating her parents. A skull is discovered on a fishing boat.

A pattern emerges as Ji-a looks into the island's history of strange and suspicious deaths. Lee Rang keeps Yeon distracted.

Rang pledges to hurt Yeon for his past actions. Before leaving for hell to serve his punishment, Yeon enjoys a home-cooked meal with Ji-a.

As he recovers, Yeon opens up to Ji-a about his first love. Rang and Ki Yu-ri are unable to ignore a creature that is crying out for help.

While seeking information about Ji-a's parents, Yeon is reunited with an old acquaintance. Rang tries to get his hands on a valuable artifact.

Worried that Ji-a might not be safe without her fox marble, Yeon insists on keeping a close eye on her. Rang loses his special eyeglasses.

The eyeglasses give Ji-a a peek into her tragic history with Yeon. A woman in green traps Rang and Ji-a inside their own minds.

Inside the forest of demons, Rang and Yeon fight to survive. Elsewhere, Ji-a begins to forget reality as she gives into a fantasy.

Rang seeks a way to release himself from the binding debt he owes Kwon Hae-ryong. At work, Ji-a's team welcomes a new intern.

In a confrontation with Yeon, Imugi demonstrates the terrible power he possesses. A visit to death's door yields long-sought answers for Ji-a.

Imugi interrupts Ji-a's newfound happiness with an unsettling appearance in her dreams. Yu-ri temporarily loses control over her actions.

With new revelations weighing heavily in their hearts, Ji-a and Yeon go on a getaway. Yeon identifies a weapon that could be the key to defeating Imugi.

A mysterious plague sweeps across Seoul. Knowing that Ji-a's life is in greater danger than ever, Yeon proposes a risky alliance.

While Yeon prepares to carry out his plan to put an end to Imugi's terror, Ji-a resolves to protect Yeon. Taluipa arrives at a difficult decision.

Unable to move on, Ji-a begins a special project. Meanwhile, Rang refuses to give up on finding a way to bring Yeon back.
