Dayoung of WJSN is making waves with her solo debut, as her single "Body" continues its impressive climb on major music charts.

Released on September 9 as part of her digital single "gonna love me, right?", "Body" has seen steady momentum since its debut. As of October 15, the track ranked No. 9 on Melon's Top 100 and No. 3 on the Hot 100 (within 100 days) chart.

Rapid Chart Climb

On Melon's weekly chart for the second week of October, "Body" soared to No. 20, jumping 22 spots from the previous week. The track also ranked No. 3 on Bugs' real-time chart, No. 4 daily, and No. 5 weekly, while maintaining strong positions on VIBE and Genie as well.

Viral Sensation on Short-Form Platforms

The song's success has been amplified by the "Body Challenge" on TikTok and YouTube Shorts. Dayoung sparked the viral trend herself, uploading dance challenge clips that captured the song's fun, confident energy.

"Body" combines rhythmic beats, an addictive hook, and Dayoung's refreshing vocals, reflecting her sincerity and determination as she embarks on her new solo chapter.

A Strong Start to Her Solo Career

Dayoung's hard work is already paying off — on September 23, she earned her first-ever music show win on SBS funE's "The Show" with "Body."

(Cultural context: In K-pop, a solo debut that achieves rapid chart growth and sparks viral challenges is seen as a key indicator of public recognition — especially meaningful for idols branching out from established groups like WJSN.)
