Singers Haru and Kim Da-hyun have drawn attention with a distinctive duet stage, breathing new life into the classic song 'Jeonhwatongsin' (Telephone Conversation).

The performance aired about two months ago on MBN's 'The Legendary Man.' Rather than simply singing together, the two exchanged the song's story back and forth as if in dialogue, carrying the stage forward. With staging that revived a retro atmosphere, Kim Da-hyun's bright energy blended with Haru's voice, and viewers responded that the pairing felt fresh, with some saying the emotions of the past were reborn on today's stage.

The duo's chemistry stood out as much as the song itself. Scenes where they passed lyrics back and forth like conversation added fun, creating the feel of a short musical. In particular, expressions that brought out the song's story, including the line 'This is the young man from Cheongpa-dong,' made the old-fashioned sentiment of 'Jeonhwatongsin' all the more vivid.
