Nowhere to Hide (1999). Ahn said, "If we did not sustain our 20-year friendship, we could not have done justice to the touching scenes in Radio Star.

If visual media is regarded as a channel for spreading fully constructed images, then the radio can be seen as one that encourages people to use their imagination. Success does not necessarily mean happiness, nor does failure mean unhappiness. Through this film, people
