Singer Ailee has shared her deep sorrow over the sudden passing of Wheesung, expressing her heartbreak in an emotional tribute.
On March 11, Ailee took to social media to remember her close friend and mentor. She wrote, "Oppa… I cried so much yesterday… I was looking for pictures of us together, but I couldn’t find a single normal one… That’s so like us."
She continued, "That’s just who we were… I was watching our past performances, and we were so happy, weren’t we? I should’ve done more shows with you… Sometimes, you were a strict producer… sometimes, you were like a real older brother who lived to tease me… and other times, you were the most incredible senior artist… You know you were the most precious person in my life, right?"

Ailee went on to pour her heart out, saying, "You’re the reason I can still sing in Korea today. I’m so grateful to you—more than words can say. My best stage partner ever… it was you, and it will always be you. Oppa, thank you so much… I’m so sorry… and I’m going to miss you so much. One day, let’s meet again and sing our hearts out while laughing together… goodnight, Realslow."
According to his agency, Tajo Entertainment, Wheesung was found in cardiac arrest at his home in Gwangjin-gu, Seoul, on March 10. He was just 43 years old.
The agency released a heartbreaking statement: "He was found in cardiac arrest at his home in Seoul and was pronounced deceased. It breaks our hearts to share this devastating news with the fans who have always given Wheesung their unwavering love and support. We ask that you pray for his peace and allow him to rest in comfort."

Born in 1982, Wheesung debuted in 2002 with his first full-length album Like A Movie, quickly rising to fame with hit songs like Incurable Disease, Insomnia, and Even Thought of Marriage. His powerful voice and emotional performances left a lasting impact on K-pop and R&B.
As fans and fellow artists continue to mourn his passing, Ailee’s heartfelt words remind everyone just how much Wheesung meant to those around him. May he rest in peace.
