Whale Star: The Gyeongseong Mermaid

"Whale Star: The Gyeongseong Mermaid" is an upcoming Korean drama that promises a captivating blend of romance, history, and emotion.

Overview

"Whale Star: The Gyeongseong Mermaid" (native title: "고래별") is a historical romance drama based on the popular Naver webtoon of the same name by Na Yun-hee. It reimagines Hans Christian Andersen’s “The Little Mermaid” in the turbulent setting of 1926 Gyeongseong (present-day Seoul) during the Japanese occupation. The story explores the passionate romance and struggles of young people fighting to protect their country and loved ones in an era of loss and resistance.

The drama is co-directed by Heo Jin-ho (known for films like “Christmas in August” and “One Fine Spring Day”) and Yoo Bum-sang (director of “Twinkling Watermelon” and “Study Group”). The screenplay is written by Moru and Seol-sup. It is a 12-episode series planned for broadcast on tvN in the first half of 2027, with production by Studio Dragon and Take One Studio.

Plot Synopsis

In 1926 Gyeongseong, the story follows Kang Ui-hyeon, a dedicated independence fighter with a pro-Japanese father, and Heo Su-a, a kind-hearted maid in a pro-Japanese household. Their lives intertwine when Heo Su-a rescues Kang Ui-hyeon after he falls into the sea during a mission with fellow fighter Song Hae-su. What begins as an act of kindness blossoms into a profound connection, as the two see in each other a symbol of their homeland and hope amid oppression.

The narrative weaves together themes of love, sacrifice, national identity, and resilience, portraying the fiery passions and quiet strengths of youth navigating a time when voicing resistance could cost lives. Supporting characters, including independence movement figures and those entangled in political ambitions, add layers of tension and emotional depth to the central romance.
