The episode begins with Kang Eun Hwan (Kim Min Seok) threatening Hae Na to expose her secret as time’s running out to break her curse. Sensing the urgency, her family hurries to wipe out all the evidence Eun Hwan has gathered.
As suspicions surrounding Hae Na continue to grow, Seo Won spots a bunch of students watching Eun Hwan’s video. He quickly senses a possible link to Hae Na and heads to Eun Hwan’s hideout, only to end up caught in a trap.
As the clock ticks toward midnight, Eun Hwan calls Hae Na over to his place, telling her that Seo Won has passed out. Just as her secrets were about to be revealed on Eun Hwan’s live broadcast, Seo Won swoops in and rescues her.
Seo Won takes it slow as Hae Na tries to share the secret with him. He goes ahead and kisses her, even as she turns into a dog right before his eyes. And that’s when Hae Na’s curse is finally lifted.
In the epilogue, Seo Won and Hae Na admit their feelings for each other with Seo Won saying, “I love you” to Hae Na. Meanwhile, Lee Bo Gyeom (Lee Hyun Woo) turns out to be the mountain god who cursed Hae Na’s ancestors, leaving everyone curious about what will happen next.
