Just as excitement reached a fever pitch for their comeback, beloved fourth-generation girl group H1-KEY has sent shockwaves through their fanbase by unexpectedly canceling multiple scheduled activities, including high-profile radio appearances.

In a swift turn of events, three major SBS radio programs—Bae Sungjae’s Ten, Wendy’s Young Street, and Cultwo Show—revealed sudden changes to their guest lineups. Although not every announcement explicitly mentioned H1-KEY, the group was originally slated to promote their upcoming release on these shows.

On June 24, Bae Sungjae’s Ten put out a revised guest notice that swapped H1-KEY with another artist duo, just a day after Wendy’s Young Street announced the girl group's exit from their guest list. Cultwo Show hosts even shared their genuine surprise on-air regarding the timing of H1-KEY's cancellation.

The intensity of these abrupt changes, particularly within the same broadcast network, has left fans buzzing with speculation. Questions are swirling about whether the group’s absence is due to internal decisions or possibly more serious circumstances.

To make matters more perplexing, the timing of these cancellations couldn't be worse—H1-KEY is on the brink of releasing their fourth mini-album, *Lovestruck*, on June 26 (KST), marking a major comeback nearly a year after their last project. Typically, promotional appearances are essential for building momentum before an album drop, making the group's sudden silence all the more baffling.

As of now, fans are anxiously awaiting an official statement from H1-KEY’s agency or SBS, hoping to shed light on this unforeseen situation. What’s really going on behind the scenes? Only time will tell, but fans have every reason to be concerned.
