Seo In Young drew attention with a powerful appearance at Waterbomb Sokcho 2026, showing off the results of the intense preparation she had been sharing before the event.
On August 22, the official Waterbomb social media account uploaded a performance clip with the caption, “If you ask what a queen is, look at Waterbomb Queen-derella Seo In Young.”
Seo In Young took the stage in Sokcho and performed several of her well-known songs, including Cinderella.
For the performance, she appeared with short blonde hair and a white bodysuit decorated with silver details, creating a bold look that matched the festival atmosphere.
She also showed strong live vocals throughout the stage. At one point, the crowd loudly chanted her name, and Seo In Young appeared visibly moved by the response.
Her appearance attracted even more attention because she had openly documented her efforts to prepare for Waterbomb through her YouTube channel.
During a previous video, Seo In Young joked about wanting a more defined figure after seeing Jo Min Ah’s abs.
When the production team teased her by saying, “Right now, it’s belly-fat-bomb,” Seo In Young replied confidently, “Just wait. I’m going to lose it.”
She later revealed that she had undergone liposuction as part of her body-management process after struggling to reduce certain areas despite dieting.
Seo In Young said, “I was dieting really intensely, but my arms just wouldn’t slim down.”
She also joked about how seriously she was preparing, saying, “I put my life on this. I paid for it myself. I really spent all the money, even my appearance fee.”
After weeks of preparation, Seo In Young’s Waterbomb Sokcho 2026 stage became a chance for her to show both her transformation and the confident performance style longtime fans know her for.
