NMIXX member Sullyoon recently moved fans to tears after showing professional spirit despite suffering from physical pain during a concert.

Recently, a post titled “Sullyoon performing while crying” has been spreading rapidly across social media and online communities.
The shared video captures a moment from NMIXX’s ongoing world tour. In the clip, Sullyoon is seen on stage visibly struggling with sudden back pain.
Throughout the performance, she was spotted touching her lower back and moving with extreme caution. Despite her efforts to endure the pain and finish the set, she eventually broke into tears, leaving fans deeply concerned.
As the video gained traction, Sullyoon took to a fan communication platform to clarify the situation and reassure her supporters.
“I think I overexerted myself during the dress rehearsal yesterday, and it started hurting then. I applied pain relief patches and took medicine before sleeping, but when I woke up, it felt a bit worse,” she explained.

She further revealed her determination to perform despite medical advice, explaining that she informed the staff and received laser treatment along with various other therapies. She emphasized that both the company and the hospital suggested she should rest, but it was entirely her own will to stand on the stage, even if just for a little bit.
NMIXX is currently in the midst of their first-ever world tour. Starting with Bangkok on the 13th, the group is scheduled to visit five major Asian cities, traveling through Singapore, Kaohsiung, Hong Kong, and Tokyo.
Fans continue to send messages of support, praising her dedication while urging her to prioritize her long-term health.
