Cheongwol Blue Moon ((install)) Online

The 2024 hit drama Blue Moon of Cheongwol (starring IU and Byun Woo-seok) reframed the legend as a time-slip romance. In the show, a modern photographer captures the blue moon on her phone — only to be transported to Joseon-era Cheongwol, where she must break Wol-ha’s curse. The drama’s signature line — “Even a false moon keeps its promise once every two years” — went viral, turning the event into a romantic metaphor for rare, doomed love.
