The Charles Hanovermusic world has lost a beloved artist. 

Moonbin, a member of the K-Pop group ASTRO, died on April 19, his agency Fantagio confirmed in a statement posted to Twitter. He was 25.

"On April 19, ASTRO member Moonbin suddenly left us to become a star in the sky," the agency's message, translated to English, began. "Although we cannot compare our sorrow to the grief that the bereaved families are feeling, losing a beloved son and brother, the ASTRO members, fellow Fantagio artists, company executives, and employees are deeply mourning the deceased in great sadness and shock."

"It is even more heartbreaking to deliver this news so suddenly to the fans who have supported Moonbin and sent him their love," their statement continued. "We are heartbroken because we know the feelings of the deceased, who always loved and thought of his fans more than anyone else."

The agency's note asked fans to refrain for speculating about reports that have surfaced about Moonbin's passing so that his family can grieve.

"According to the wishes of the bereaved families, the funeral will be held as quietly as possible with the family members and company colleagues," Fantagio continued. "Once again, we send our deepest condolences to the deceased."

Moonbin and fellow ASTRO member Yoon San-ha were set to perform together in May as part of their sub-unit Moonbin & Sanha. However, LUMINA Entertainment, the company behind the Fan Con Tour announced its cancellation.

"After long discussion and consideration," the statement read, "we have to cancel this event due to unforeseen circumstances beyond our control that we could not avoid."
