Dayoung takes 'body' from Shorts buzz to her first solo win

WJSN Dayoung's solo song 'body' is a track that gained late momentum on charts and stages following its release in September 2025. Her appearance on MBC 'Radio Star' on June 10, 2026, is more than just a variety show appearance. It is a broadcast that revisits how Dayoung, standing as a solo artist nine years after her debut, carved out her own space.

The core is not the 12kg weight loss itself. Rather, it is the fact that the time spent building her physique, finding the right song, and personally enduring the pace of the stage translated into the song's persuasiveness.

First Solo Win with 6,590 Points on 'The Show'

'body' launched as the title track for her first digital single, 'gonna love me, right?'. Rather than a song pushed solely by overwhelming fandom power from the start, it was a track that grew as stage videos and short clips circulated, increasing the number of listeners.

Dayoung claimed her first solo music broadcast win on SBS funE 'The Show' on September 23, 2025, with 6,590 points. Subsequently, her rankings rose on domestic music charts. While a group member's first solo can gain initial interest due to their name value, sustaining that interest through the following weeks and months requires the song and the performance to hold their own strength.

Dayoung debuted with WJSN in 2016 and long presented a bright and friendly image within the group. Therefore, the achievement of 'body' was a more demanding task than a simple image transformation. She had to make a familiar face appear in an unfamiliar tone while simultaneously providing assurance that she could sustain a solo stage alone.

Melon TOP100 10th, Bugs Real-time 2nd

The confirmed results point in one direction. As of 9 AM on October 10, 2025, 'body' reached 10th on the Melon TOP100, 5th on the Melon HOT100, and 2nd on the Bugs real-time chart. On the YouTube daily Shorts popular song chart, it ranked 9th, and on the weekly Shorts popular song chart aggregated from September 26 to October 2, it recorded 13th.

While each ranking is a record of a short moment, the fact that the music charts and Shorts charts moved together is noteworthy. Rather than explaining it solely as a result of fans repeating the track, it is closer to a structure where the stage energy seen in short videos led back to music streaming.

Melon and Bugs show music consumption, while the Shorts chart shows how much a song is used in short videos. 'body' touched both sides simultaneously. The movements and expressions Dayoung showed on stage, along with the addictive chorus, suited short videos, and that short impression is read as a case that called for listening to the full song again.

12kg Weight Loss Over One Year, Aiming for Stage Stamina

It is known that Dayoung lost approximately 12kg over about one year. While this number easily becomes a hot topic, the part that needs to be viewed more closely is the purpose of the weight loss. Dayoung explained that she built her physique to sing and dance for longer periods, choosing a method of losing 1kg per month.

A K-pop solo stage keeps the camera on one person for a long time. In group performances, member movements and part distributions share the breathing, but in a solo song, stamina, facial expressions, and gaze management are concentrated on one person. As 'body' is a pop dance track, this preparation is closer to performance sustainability than mere physical change.

This direction is also clear in the official MV. Bright LA backgrounds, fast movements, and close camera work follow, and Dayoung leads the screen in a way that does not lose her center among the dancers. Since the refreshing vocals in the chorus and the short, staccato choreography move together, the charm of the song is only half-visible through the music alone. The song explained the stage, and the stage sold the song.

Solo Behind-the-Scenes Stories on 'Radio Star' on June 10

It is known that during her solo preparations, Dayoung went to LA in the US to pursue recording work, and she has continued English studies and communication with overseas collaborators. In an overseas interview released in 2026, she spoke about the concept that she must now take individual responsibility for the choices and concepts she once shared within the group.

Indeed, Dayoung opened a new chapter in 2026 with 'What's a girl to do'. If 'body' was closer to a summer night's pop dance energy, the new song puts pop and R&B sensibilities more at the forefront. It is a process of testing the confidence gained from her first solo song through a different texture.

'Radio Star', broadcasting at 10:30 PM on the night of June 10, will cover the behind-the-scenes stories of Dayoung's solo success, the LA recording process, and her connection to the music video with Shiloh Jolie. Dayoung has crossed the starting line as a solo artist with 'body'. Attention is focused on how she will carry the flow of 2025—where chart rankings, music show trophies, and Shorts reactions all aligned—into her 2026 activities.
