In a concerning update for fans of THE BOYZ, it has been officially confirmed that member Sunwoo will be unable to participate in his scheduled activities for the popular radio program Idol Radio.
On January 2, 2026, his agency, IST Entertainment, released a statement informing the public that the artist is currently dealing with health-related issues that require immediate rest and medical attention.
As a result, he will be taking a temporary hiatus from his role as a DJ to focus on his recovery.
Medical Assessment and Hiatus Details
According to the official statement, Sunwoo recently visited a medical facility after experiencing persistent physical discomfort and fatigue.
Following a thorough examination, medical professionals advised that he undergo a period of stability and intensive rest to prevent further complications.

While the specific nature of his condition was not disclosed in detail to protect his privacy, the agency emphasized that the artist’s health is their absolute top priority.
Sunwoo has been a beloved fixture on Idol Radio Season 4, having served as a DJ since early 2024.
His absence will be felt deeply by the show’s listeners, but IST Entertainment has requested the understanding of fans, stating,
“We ask for your kind consideration as this decision was made to ensure the artist can return to the stage and the radio booth in a healthy state.”
Interim DJ Arrangements
To ensure the continuity of the program during Sunwoo’s recovery, the production team of Idol Radio is making temporary adjustments.

Fellow THE BOYZ member Eric, who joined as a permanent DJ in early 2025 to co-host with Sunwoo, is expected to take on a larger role in the short term.
Additionally, special guest DJs from other K-pop groups may be brought in to fill the vacancy for certain episodes.
The agency has promised to provide regular updates on Sunwoo’s condition and will notify fans as soon as a return date is confirmed.
For now, all of his other scheduled group activities are also being reviewed and adjusted based on his recovery progress.
A Pattern of Physical Strain
This recent health setback has reignited concerns among the fandom, known as THE B, regarding the group’s grueling schedule.

Fans have taken to social media with the hashtag #GetWellSoonSunwoo, urging the agency to prioritize the long-term well-being of all members over their busy promotional cycles.
Despite these challenges, Sunwoo’s dedication to his craft remains unwavering. In his own messages to fans prior to the official announcement, he expressed regret for causing worry and promised to work hard on his rehabilitation.
Looking Ahead to 2026
As THE BOYZ approach their ninth year in the industry, the group is at a pivotal stage of their career.
With several major projects rumored for the first half of 2026, including potential solo ventures and a new group comeback, Sunwoo’s recovery is crucial for the team’s momentum.
The industry and fans alike are wishing for a swift and complete recovery for the talented rapper and DJ.
His absence serves as a poignant reminder of the physical and mental demands placed on idols who strive to maintain a constant presence in the fast-paced world of K-pop.
As Sunwoo takes this necessary time for himself, the “Idol Radio” family and THE B community stand ready to welcome him back with open arms once he is fully healed.
