Millie Seojae began offering its e-book subscription service in 2017, entering South Korea's emerging digital reading market. The platform distinguished itself by offering unlimited access to a broad catalog of e-books, audiobooks, webtoons, and web novels rather than selling titles individually. Over the following years, it expanded its publisher partnerships to approximately 2,000 publishing houses, building a large library of Korean-language content. By the end of June 2023, the service reported holding about 150,000 reading content titles. The company became affiliated with KT Corporation, a major South Korean telecommunications and media conglomerate, and is commonly known as KT Millie Seojae.
