Island - Episode Guide

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. Mi-ho is sent to Jeju Island until things quiet down, but she comes across a lust demon in a wedding dress.

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. But before she could get on a plane, she ended up in a life-threatening car chase with a lust demon.

Johan moves into Mi-ho's villa to live with Van and Mi-ho, disguised as Butler Jang'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. Meanwhile, Su-ryeon, a Tamra High School student, decides to go and perform rites at Benjulle's sacred tree after being threatened by her boyfriend...

A white wave emanating from Mi Ho's chest defeats Benjullae and saves the soul of Su Ryeon. Mi Ho returns to her villa and starts planning how to punish Gyeong Jun. Meanwhile, Johan provokes Van to find out his identity, summoning the hidden nature of the lust demon. Mi Ho comes to look for Van and Johan and sees Van transforming into a lust demon. While Mi Ho is shocked, Van comes rushing at her.

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. Meanwhile, the number of mysterious murder cases where the organs were extracted from the victims is increasing all over Jeju Island.

Jo Han brings Chan Hee to the villa. They spend time happily together, promising each other that they will not part again. However, Chan Hee has already turned into a lust demon, and he leaves Jo Han's room to go after Mi Ho's life. Meanwhile, after finding out about the secret of reincarnation, Mi Ho visits and asks Geum Baek Ju to help her become Won Jeong.

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. Ten years later, Wonjeong returns to Taejangsa Temple after completing her training to establish the Barrier. However, as soon as she starts establishing the Barrier, Jongryeong tries to burn Van and Gungtan, and the Taejangsa Temple becomes a scene of carnage.

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. From then, she begins receiving intense training from Geum Baek-ju at Granny Haenyeo's Home to regain the power of Wonjeong. Johan and Van follow Mi-ho but observe from a distance so that they don't interrupt her energy. Meanwhile, more of Gungtan's past and why the mysterious people awakened him are revealed.

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 starts to blame herself, believing that the tragedy will only end when she dies. Meanwhile, illusions of Gusunsae cause Tamra High School students to engage in mass suicide. Despite Johan's effort to try to save the students, it wasn't enough. However, with the help of Butler Jang, Van and Johan work together and save the students.

Mi-ho finds out about Butler Jang'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. Gungtan rages as he feels dejected after watching Mi-ho fail to regain power even after her memory has returned. Filled with madness, Gungtan prepares for the end by brutally killing the tramps he has given shelter to. Meanwhile, Butler Jang is remorseful for keeping a secret from Mi-ho and decides to leave the mansion.

Van learns that Mi Ho will vanish, leaving only Wonjeong, if she regains her power. After agonizing, Van tries to stop Mi Ho's training to become Wonjeong. Mi Ho is frustrated and upset with Van's sudden behavior. Meanwhile, Gungtan attempts to use Yeom Ji to find out about the location of the remaining Dol Hareubang, and Johan goes to Gungtan's hideout to fight him in order to save Geum Baek Ju and Yeom Ji.

It's finally the day to establish the Barrier. Mi Ho, on her way to the altar, fights a great battle against lust demons alongside Butler Chang, who has returned, and Johan, who woke up from a coma. After defeating countless lust demons, Mi Ho leaves the rest to Van, Johan, and Butler Chang and goes up to the altar, but her memories from the past and fear hinder her.
