BLACKPINK's Jennie made her explosive solo comeback earlier this month, with the full album 'Ruby.' To commemorate the occasion, Jennie held a special concert series 'The Ruby Experience,' ending with a final concert in Incheon.
But the most unexpected audience members of all turned out to be NJZ (NewJeans). All five NJZ members were seen attending the concert, with those around them reacting in shock to their appearance. The audience screamed and cheered for NJZ, with many filming the members, reaching out for them, and standing to try to get a better view of the unexpected guests.
