The Waterbomb Sokcho 2026 festival featured performances by K-pop artists Seo In Young and (G)I-DLE’s Soyeon. Soyeon used the stage to preview tracks from her upcoming solo album, though her choreography and outfit sparked debate among fans.

Seo In Young’s performance marked a significant career resurgence. She performed hits such as ‘Cinderella’ and ‘Thank You’ alongside a dance team led by Aiki. To prepare for the event, Seo revealed she underwent a rigorous transformation, including losing 15kg to reach a weight of 46kg through a protein-centered diet and undergoing arm liposuction. Her comeback follows a period of public reconciliation via her YouTube channel, where she addressed past controversies.
