Island

Won Mi-ho is the only heiress to the Daehan Group. She falls for her aunt’s plot and becomes the center of a controversy after beating up a person in the middle of the city.

Not only was Mi-ho chased twice by lust demons, but the police are now also treating her like a drug user. She is trying to come up with a plan to escape Jeju Island and go back to Seoul.

Johan moves into Mi-ho’s villa to live with Van and Mi-ho, disguised as Butler Chang’s nephew. Mi-ho is displeased with Van, who doesn’t seem to cooperate and can’t even drive a car. On top of that, Johan starts tagging along to school.

Mi-ho meets the last of Benjulle’s trees after a fierce battle in Benjulle’s forest. Mi-ho returns to her villa after saving Su-ryeon and starts planning on how to punish Gyeong-jun.

Van feels guilty for nearly killing Mi-ho and disappears into the darkness. To find Van, Mi-ho goes through rough mountain tracks to Taejangsa Temple, only to walk away after being hurt by his coldness.

Johan brings Chan-hee to the villa. They spend time happily together, promising each other that they would not part again. However, Chan-hee has already turned into a lust demon, and he leaves Johan’s room to go after Mi-ho’s life.

Long ago, Jeju was thrown into confusion by an outbreak of lust demons. Wonjeong, fated to save the island by establishing the Barrier, secretly visits and forms a friendship with two boys, Van and Gungtan, who were raised solely to kill lust demons.

Johan overcomes his despair after Chan-hee's death. Mi-ho, who is in pain and blaming herself, vows not to lose anyone else who is precious.

Gungtan remembers once again that Wonjeong had sealed him in the past and escapes without being able to harm Mi-ho. Captivated by fear and anger, Gungtan begins to plunge the world into darkness.

Mi-ho finds out about Butler Chang's secret and tries to kill herself as she feels betrayed. The moment Van rushes to Mi-ho and holds her hand, she recovers all the memories from the past.
