While fulfilling her part of the deal with a so-called "fairy," young Jin Seonmi makes a critical mistake that catches up with her 25 years later.

Desperate for help in dealing with Son Ohgong, Seonmi seeks out Demon King Woo (Woo Mawang), who, as the head of an entertainment agency, is judging for an audition.

As Geumganggo works its magic on Ohgong, he gets frustrated by the conflicting feelings he has toward Seonmi. Meanwhile, a young woman goes missing.

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

Demon 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 Jiyoung can't allow herself to just watch as Demon King suffers. Seonmi feels torn as she knows all too well that Ohgong's love isn't real.

Demon King seeks Seonmi's help in dealing with a troublesome prince who refuses to return home until he finds a runaway mermaid.

When the plan to make Ohgong jealous misfires, Demon King shows Seonmi something to provoke her. An evil spirit is using social media to spread hate.

Seonmi 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 Seonmi's wish to be ordinary has far-reaching consequences on not only Ohgong but also Demon King, Zombie, and even P.K (Jo Palgye).

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

Ohgong realizes that the Geumganggo has the power to take his life. Kang Daeseong devises a plan to get rid of his annoyances altogether.

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

Relentless in her desire to be stronger, Sanyeo orders General Winter to get her incense burner back. Seonmi mentions the love bell to Ohgong.

To avoid exacerbating the dilemma regarding Sanyeo, Ohgong must pretend not to know the truth, and General Winter must be found as soon as possible.

In an uncanny dream, a woman shows Ohgong the moment that Samjang was born. Sanyeo demonstrates what she's capable of doing for Daeseong.

Ohgong refuses to accept his and Seonmi's fates. Demon King wants to believe Sanyeo despite others' warnings that he's being deceived.

As Ohgong prepares to sacrifice himself in place of Seonmi, Demon King, feeling sorry for both, tries to solve the mystery behind the Geumganggo.

While Seonmi is away at the Lotus Village trying to figure out exactly what her mission is, Ohgong hurries to begin the ritual to summon the dragon.

Both the Spiritual Realm and Demon King try to get Ohgong to come out of Sureumdong, where he's shut himself in after the fateful day.
