ChaO, set in a future world where humans and mermaids coexist, follows the main character, Stephan, an ordinary human who unexpectedly ends up marrying the mermaid kingdom's princess. The film is anything but ordinary, filled with unique elements that powerfully explore mermaids, humans, and the future—from its animation to its story. Over the course of nine years, it was meticulously hand-drawn, producing more than 100,000 frames that vividly depict a fantastical world where various species coexist. From the water spray scattering like flower petals to the chaotic married life of the protagonists and their journey to uncover a hidden past, ChaO captivates. Anyone who watches the film sincerely hopes that Stephan and ChaO will live “happily ever after." (KIM Yunha)
