She Would Never Know (2021)

Based on a popular 2017 Web Novel of the same name. It tells the love story between a lovely “sunbae” (someone senior at work, school, or in an industry) and a bold “hoobae” (junior) who has it all: good looks, cuteness, sexiness, and a serious aura. Won Jin Ah takes on the role of Yoon Song Ah, who works at a cosmetics company as a professional brand marketer. She dreams of having her own cosmetics brand one day. Rowoon will play the straightforward hoobae cosmetics brand marketer Chae Hyun Seung.
