As Geumganggo works its magic on O-gong, he gets frustrated by the conflicting feelings he has toward Seon-mi. Meanwhile, a young woman goes missing.

To get O-gong off his back, Devil King is forced to make a big compromise. O-gong brings something -- or someone -- very stinky to Devil King's house.

Devil King donates an object of cultural importance to a museum, where historical artifacts on exhibit still bear the souls of the original owners.

Loyal Ms. Ma can't allow herself to just watch as Devil King suffers. Seon-mi feels torn as she knows all too well that O-gong's love isn't real.

Devil King Woo seeks Seon-mi's help in dealing with a troublesome prince who refuses to return home until he finds a runaway mermaid.

When the plan to make O-gong jealous misfires, Devil King shows Seon-mi something to provoke her. An evil spirit is using social media to spread hate.

Seon-mi can't stop thinking about the moment the bell rang and what it means for her. An evil spirit is suspected of stealing children's souls.

The fulfillment of Seon-mi's wish to be ordinary has far-reaching consequences on not only O-gong but also Devil King Woo, Richie and even Pal-kye.

An assailant attacks Devil King Woo at a torch relay. Richie prepares to say her goodbyes. Ms. Ma finds out that a black bell has gone missing.

O-gong realizes that the Geumganggo has the power to take his life. Kang Dae-seong devises a plan to get rid of his annoyances altogether.

Asanyeo pursues what she didn't achieve more than 1,000 years ago. Aware of Devil King Woo's weakness, she decides to use it to her advantage.

Relentless in her desire to be stronger, Asanyeo orders General Winter to get her incense burner back. Seon-mi mentions the love bell to O-gong.

To avoid exacerbating the dilemma regarding Asanyeo, O-gong must pretend not to know the truth, and General Winter must be found as soon as possible.

In an uncanny dream, a woman shows O-gong the moment that Samjang was born. Asanyeo demonstrates what she's capable of doing for Kang Dae-seong.

O-gong refuses to accept his and Seon-mi's fates. Devil King Woo wants to believe Asanyeo despite others' warnings that he's being deceived.

As O-gong prepares to sacrifice himself in place of Seon-mi, Devil King Woo, feeling sorry for both, tries to solve the mystery behind the Geumganggo.

While Seon-mi is away at the Lotus Village trying to figure out exactly what her mission is, O-gong hurries to begin the ritual to summon the dragon.

Both the Spiritual Realm and Devil King Woo try to get O-gong to come out of Sureumdong, where he's shut himself in after the fateful day.
