K-pop star and former F.ABLE member Jaehyun has died, aged 23

K-pop musician Shim Jaehyun has died. He was 23 years old.

News of the singer’s death began spreading on Sunday (June 29) through his friends and acquaintances, and was later acknowledged publicly by his former F.ABLE bandmates and other members of the K-pop industry.

Per a Billboard report, Jaehyun was battling leukemia at the time of his death – a condition he kept private. It is reported that his former bandmates were unaware of his leukemia battle until after his passing.

Jaehyun’s former bandmate Hojun later paid tribute in a now-expired Instagram post that include several pictures of them together: “Jaehyun, I heard the news too late… I’m so sorry I couldn’t be there for your last journey. I sometimes think about how I could have done better, and it’s regretful. I hope you can shake off all your worries and live comfortably there. Thank you for the past five years. I hope you’re eating lots of delicious food and doing well there. Come visit me in my dreams.”
