WJSN's Dayoung and Jay Park to Release First Collaboration Single in August... New Song After 4 Months

WJSN’s Dayoung will release a collaboration single with Jay Park for the first time since her debut. The teaser image featuring Dayoung and Jay Park was released on various social media platforms on July 28. The upcoming collaboration single is set to be released in August, and the black-and-white vintage-style teaser image caught attention. The image shows the two naturally conversing or holding hands while walking down the street. Dayoung and Jay Park’s connection began last December at the 2025 Melon Music Awards (MMA 2025). At that time, Dayoung appeared as a surprise guest on Jay Park’s stage, marking their first joint performance. Then, on the 25th, Dayoung joined Jay Park on the ″Waterbomb″ stage, and a unit teaser image was released immediately after the performance. This single is Dayoung’s new song about four months after releasing her second digital single, ″What’s a girl to do,″ in April. Since her solo debut, Dayoung has actively participated in album planning, production, songwriting, and composing, demonstrating musical authenticity and her capabilities as an artist. She has established her identity as a solo artist by actively reflecting her ideas in the concept, sound, visuals, and overall work. Information about Dayoung and Jay Park’s collaboration single will be gradually released along with various content in the future.
