One of the most praised aspects of Twinkling Watermelon is its respectful and highly accurate representation of the deaf community. Actress Shin Eun-soo, who portrays the younger version of Eun-gyeol’s mother, Yoon Chung-ah, spent months mastering sign language to deliver a visceral, deeply emotional performance without speaking a word of spoken dialogue. The drama successfully balances the beauty of visual communication with the harsh societal isolation often felt by disabled individuals in the 1990s. 2.
