With just 30 days left until the highly anticipated concert, Sandara Park of 2NE1 has shared a glimpse of her grueling rehearsal schedule, raising concerns among fans about her well-being.

On September 3rd, Sandara posted several photos on her Instagram with the caption, "Morning practice today!" In the photos, she is seen sitting on the floor of a rehearsal studio, dressed in black training pants and a white and black top. Her tired expression, likely due to the continuous rehearsals leading up to the concert, has drawn sympathy from fans.

Sandara, who recently revealed that she weighs only 39kg, appears to be feeling the physical strain of the intense preparations for the upcoming performance. Fans are expressing concern, noting her exhausted demeanor in the photos.

2NE1 is set to hold their '2024 2NE1 CONCERT [WELCOME BACK] IN SEOUL' from October 4th to 6th at the Olympic Hall in Seoul's Olympic Park. Following the Seoul concerts, the group will head to Kobe World Hall in Japan at the end of November, and then to Tokyo’s Ariake Arena in early December. Additionally, the four members are expected to announce a more extensive Asia tour schedule, expanding their reach to more fans across the region.

As the concert date approaches, fans are hoping that Sandara and her fellow members will take care of their health and deliver a spectacular performance.
