NMIXXs Sullyoon to Perform Seated at Singapore Show Amid Back Pain

On June 18, 2026, JYP Entertainment announced that NMIXX member Sullyoon will perform seated during the group’s upcoming concert in Singapore. The decision follows a recent hospital visit for back pain and a medical evaluation that advised against strenuous choreography.

Sullyoon, one of the six‑person K‑pop girl group NMIXX, has been grappling with back discomfort that began after an overexertion episode during rehearsals. In a statement released by JYP, the agency said the singer “recently visited the hospital due to her back pain and underwent a thorough medical evaluation.” Medical staff recommended that she avoid intense movements and focus on recovery. Despite the advice, Sullyoon chose to keep the show going and will sit on stage if the pain becomes severe.

The announcement came after Sullyoon’s visible struggle during a NMIXX concert in Bangkok, Thailand. Video footage showed the singer appearing to strain on stage and crying. She later explained on a fan‑communication platform that the pain worsened despite self‑care and treatment, and that doctors and the agency had recommended rest.

NMIXX’s first world tour, titled “EPISODE 1: ZERO FRONTIER,” began in Incheon, South Korea, on November 29–30, 2025. The tour has since expanded to venues in Europe, North America, and Asia, with the Singapore date scheduled as part of the second leg. The group’s lineup—Lily, Haewon, Sullyoon, Bae, Jiwoo, and Kyujin—has remained unchanged since the departure of former member Jinni in December 2022.

According to JYP, Sullyoon’s decision to perform seated reflects her “strong desire to perform and keep her promise to the fans.” The agency added that it will continue to support her treatment and recovery while prioritizing her health and safety.

The Singapore concert is expected to attract fans who have followed NMIXX’s rise since their 2022 debut with the single album Ad Mare. The group’s 2023 EP Expérgo and the 2025 studio album Blue Valentine earned chart success, with the lead single from the latter becoming the group’s first number‑one on the Circle Digital Chart.

Sullyoon’s health situation has drawn attention to the physical demands placed on K‑pop performers. The industry’s rigorous training and performance schedules are well documented, and medical incidents have prompted discussions about artist welfare.

JYP Entertainment, founded in 1997 by Park Jin‑young, operates as a multinational entertainment company that manages talent, produces music, and organizes concerts. The agency’s SQU4D division, which oversees NMIXX, has stated that it will provide “the best possible support” for Sullyoon’s recovery.

The decision to have Sullyoon perform seated is a temporary measure. No further details have been released regarding the duration of the limitation or whether additional accommodations will be made for future shows.

The Singapore venue, part of Live Nation’s network, will host the concert on a date yet to be confirmed. Ticket holders have been notified of the change, and the agency has requested understanding from fans.

The situation underscores the importance of health considerations in live performances and highlights the agency’s role in balancing artist commitments with medical advice.

As the world tour continues, NMIXX’s management will monitor Sullyoon’s condition and adjust the performance plan as needed. The agency has not announced any changes to the rest of the tour’s schedule.

The Singapore concert remains a key event in NMIXX’s international expansion, and the group’s commitment to performing, even in a limited capacity, reflects its ongoing engagement with a global fan base.

In summary, Sullyoon will perform seated at the upcoming Singapore show due to back pain, following a medical evaluation that advised against strenuous choreography. JYP Entertainment has pledged continued support for her recovery while maintaining the concert schedule.
