Over the course of the show, Ji-sun consistently ranked near the top, impressing judges with her vocal clarity and precise dance moves. In the finale, she placed first out of nine winners, securing her spot as the center of the debut lineup. That moment on November 29, 2017, was the culmination of years of training and the start of her professional career.[edit]

Roh Ji-sun debuted with Fromis 9 on January 24, 2018, with the mini-album To. Heart. The group quickly built a dedicated fanbase through catchy singles like Love Bomb and Feel Good.

Roh Ji-sun remains a central figure in the K-pop landscape, known for her enduring presence as a vocalist and dancer. While her journey with Fromis_9 has seen significant shifts following contract changes and lineup adjustments, her connection to the fanbase remains strong through shared history and continued public appearances. The collective fandom, often referred to as FANIT, continues to support the members individually even as the group navigates new chapters under different management structures. Fans frequently recall her energetic performances and cheerful interactions during live events, traits that have cemented her reputation as a reliable and beloved idol within the community. Her solo activities on social media further deepen this bond, offering glimpses into her daily life and maintaining a loyal following without a formally distinct individual fan club name separate from the group's identity. Despite the complexities of recent industry transitions, including her departure from Pledis Entertainment and subsequent move to ASND, Roh Ji-sun maintains a visible footprint in the entertainment sphere. According to iFANN's Global Fame Engine evaluation conducted in August 2026, Roh Ji-sun is currently evaluated but does not hold a placement in the published rankings such as the Global Top 1,000 or any Top-100 scope list. This status reflects a period where she is recognized by the system yet lacks a specific numeric rank at this time.[edit]

Her nickname Rosie originated from fans who noticed her naturally rosy cheeks during the variety show Idol School, a moniker that stuck throughout her career. She is well-known for her sweet tooth, particularly her love for tiramisu, which she often shares with colleagues. A disciplined habit she maintains is writing daily gratitude entries in a journal, a practice that highlights her reflective nature. Notably, she holds the distinction of being the only member of Fromis 9 to secure first place on Idol School. Her favorite color remains pastel pink, a shade that frequently appears in her fashion choices. While no specific viral legends or crowd-disrupting moments are documented solely for her individual persona in recent records, her role as the group's center during their formative years remains a cherished part of their lore. Stories from her time on Idol Room and her consistent energy as a main dancer continue to be retold by long-time supporters as defining characteristics of her early stardom.[edit]
