Echoes of the Lost City.

As a child, Airada often dreamt of a lost city that sank into a lake. She'd been told the tale of a love triangle between princess, prince and Naga, one that led to the city's ruin. Now, the dreams have returned, and she begins looking into the legend of Phadaeng Nang Ai, meeting Korawit who looks strikingly like a man she knows only from her dreams. When a news of a Naga sighting at Phadaeng Nang Ai reaches him, Korawit decides to investigate. As Airada begins questioning her connection to the past, a joint journey to uncover the truth and break the city's ancient curse begins.
