 Linked by dreams, mysterious artifacts, including the jadeite bracelet, a vase with an image of a mermaid kissing a man in modern-day clothes, and the portrait of Kim Dam-ryeong with the inscription “everything is repeating itself", Joon-jae learns of Dam-ryeong's world and his own fate, concluding that he and Shim Cheong are reincarnations of Kim Dam-ryeong and Se-hwa.Through his consultations with Professor of Neuropsychiatry Jin Kyung-won (Lee Ho-jae), he is able to retrieve his lost memories and the full rendering of his dreams about Kim Dam-ryeong and Se-hwa.He can also hear Shim Cheong's inner voice; he learns that she is indeed a mermaid and that, unless she returns to the ocean, her heart will harden and eventually stop if he will not love her.
