Public image

Moon's status as a "chaebol heiress" garnered significant attention in the South Korean media, with her debut marking the first time a member of a prominent Korean chaebol family entered the Korean idol industry. Her aspirations of becoming an idol has drawn comparisons to "a real-life scene from a chaebol drama for many Koreans". Despite skepticism from some, Moon commented, "One thing is certain: thanks to all of you, every day I feel that I made the right choice not to give up and to pursue this path."
Moon's style has also attracted the interest of the media. South China Morning Post wrote, "Moon has shown a knack for incorporating high-end designer pieces into her everyday looks, while adding a modern, edgy twist that resonates with millennials and Gen Z." In photos released to promote AllDay Project's official debut, Moon styled a Balenciaga denim miniskirt with a basic T-shirt, which was noted for evoking an urban image that subtly expressed her "upscale yet accessible fashion sense".

Influences

Moon has said from childhood she has been inspired by 2NE1 and BigBang. She cites CL as her role model.
