Jay Park, WJSN's Dayoung Spark Dating Vibes in Cozy Couch Photos

WJSN member Dayoung is teaming up with singer Jay Park for a new collaboration single. The two artists will release the track in August.

Dayoung shared a teaser image with Jay Park on her official social media on the 29th. The photos show the pair walking side by side down a street and smiling at each other, giving off an easy, natural chemistry. The images have raised curiosity about the sound of the upcoming duet.

Dayoung and Jay Park have shared several stages together over the past year. They first performed together at the 2025 Melon Music Awards and reunited most recently at Waterbomb Seoul 2026.

Dayoung has built her solo career hands-on, taking part in album planning and production as well as writing lyrics and composing music. That direct involvement has helped her shape a distinct sound and expand her work both in South Korea and abroad.

The new single from Dayoung and Jay Park is scheduled for release in August.
