WJSN's Dayoung Announces April Comeback With "What's a Girl to Do?"

WJSN member Dayoung (임다영) is heading back to her solo career with a second digital single, "What's a Girl to Do?", arriving this April. On March 22, her agency Starship Entertainment posted a teaser image across Dayoung's official social media channels alongside the phrase "COMING SOON. APRIL," officially confirming the comeback, according to Starship Entertainment's own teaser rollout. The announcement came less than eight months after Dayoung's solo debut single album "gonna love me, right?" dropped in September 2025, a project that quickly overperformed. Its title track "body" climbed to number nine on Melon's TOP100 and spent time at number 17 on the monthly chart, surpassing 10 million cumulative streams. Dayoung earned a music show win and took home Best Solo Artist (Female) at the 2025 Korea Grand Music Awards. Her debut was not a label experiment. It was a real career move, and now she is building on it.

What 'body' Built

When "body" landed in September 2025, Starship Entertainment gave it no physical release and ran a lean promotional campaign. Most of the early visibility came from Dayoung's own initiative, as fans on r/kpopthoughts noted while tracking the campaign in real time. The track is a rhythmic pop dance song built around the heat of a summer night and the pull of instinctive attraction, and Dayoung's live stage presence made it hit harder than the numbers suggest it should have. She went viral repeatedly for her music show performances, triggering TikTok challenges and collaborations with celebrities across multiple industries. "body" eventually placed in Best K-pop of 2025 roundups by NME, Billboard, and The Hollywood Reporter, as reported by HelloKpop. Teen Vogue named the music video one of the best K-pop MVs of the year. The track cleared number nine on Melon's TOP100 and surpassed 10 million total streams, a high bar for a debut digital single with no physical run behind it.

A Teaser That Knows What It Is

The comeback teaser, shared on March 22 via Dayoung's official social media and confirmed by Starship Entertainment, leans into an intense pink-toned aesthetic. The image reveals only a partial view of Dayoung's face and silhouette, and the phrase "What's a girl to do" overlaid on the visual sets a tone that is more pointed and introspective than the carefree summer energy of "body." That is a deliberate pivot. Dayoung is not repeating herself. The muted, charged quality of the tease suggests an emotionally direct concept, and the title alone asks a question that sounds like both a lament and a taunt. Whether this leads into a breakup narrative, a power anthem, or something harder to categorize is, by design, unclear until release. That slow-burn uncertainty is exactly the kind of pre-release tension that feeds engagement in a crowded April calendar.

More Than a Group Member Doing a Side Project

Dayoung debuted with WJSN (우주소녀), also known as Cosmic Girls, on February 25, 2016, and has been a member of the group's sub-unit WJSN Chocome alongside Soobin, Luda, and Yeoreum. For most of her career, her work existed within those ensemble frameworks. The solo project changed that. On "gonna love me, right?," she participated in songwriting, composing, and overall album planning, which is not standard for group idols stepping into solo territory. Fans took notice. When the label's promotional support was minimal, Dayoung drove her own campaign, doing TikTok challenge collaborations and behind-the-scenes content that kept the song circulating well past its release week. Fellow WJSN member Yoo Yeonjung has also been making moves in her own right, and the group itself returned with new music in early 2026. But Dayoung's solo output is the clearest signal yet of what she can do outside a group context.

What April Looks Like From Here

April 2026 is one of the most loaded months the K-pop industry has seen this cycle, per Korea Times reporting on the overcrowded comeback calendar. Dayoung enters that window with genuine momentum. The credibility built by "body" means "What's a Girl to Do?" is not a debut risk. It is a sophomore release backed by chart history, international press validation, and a fanbase that has already proven it will stream and show up. Her first Waterbomb festival performance is booked for July 26, 2026, placing her on one of South Korea's biggest outdoor summer festival stages. The booking did not happen because of WJSN. It happened because of "body." That distinction matters. Dayoung is no longer just a group member with a side project. She is a solo artist with a portfolio, and April is where that portfolio grows.
