Jo Jeong-min surprises at Haru fan concert with four-hands piano and rock duet

Jo Jeong-min crashed Haru's fan concert as a surprise guest. The night became a two-artist showcase.

She opened with Seol Un-do's Sister. Then the two stood at a single piano and played the theme from Secret using the four-hands standing method. The set peaked on Shin Joong-hyun's Beauty — breathless piano runs, individual solos, and vocal harmonies locked into a full rock duet.

Jo Jeong-min followed with Glass Wall and Parallel Lines, keeping the room hot before slowing down to introduce Between You, Night, and Me. She had gifted that song to Haru at the start of Haru's debut, a detail that retraced the pair's history in real time.

The two have long described their bond as that of a close older sister and younger sibling (친누나 같은 케미). The night leaned into it: music, candid conversation, and easy back-and-forth that filled the venue with both warmth and noise.
