Youilmui is a Korean serialized-fiction reading service, starting with The Goddess of Abstinence, Choi Jeonghwa. Readers can move naturally from episode to episode, save their progress, and unlock later chapters without breaking the flow of the story. The goal is simple: make long-form serialized fiction feel effortless to read. For this launch, I used GPT-6 Astra to improve the product, development workflow, and reading experience.
