On June 19, the latest episode of YouTube channel Gym Jong Kook featured Haha, his son Dream, and bodybuilder Ma Sun-ho.
While the episode centered around Haha promoting his new song “Sunny Day,” the biggest surprise came from an unexpected voice cameo.
As Kim Jong Kook brought up Haha’s album release and jokingly asked, “Can someone congratulate him?” a familiar voice suddenly chimed in, “Congrats on the album, Haha hyung,” said none other than BTS’s V, giving a thumbs-up gesture though he didn’t appear on screen. His brief audio message alone caused a stir in the studio.
Haha, visibly stunned, couldn’t hold back his laughter and subtly hinted at V’s identity by flashing a V-sign to the camera. He then shared, “He’s the one who gave a shout-out to my song on Twitter.”
Indeed, back in 2021, V had recommended Haha’s song “Story of a Short Kid” on BTS’s official Twitter, describing it as a track that “gave me great comfort when I was little.”
Their connection goes even further back to 2015 during an appearance on Mnet’s Yaman TV, where Haha was awestruck by V’s looks and repeatedly complimented him. In his 2018 song “Dang Diggi Bang,” Haha even included the line “Feeling BTS like V,” expressing his admiration.

This particular episode was reportedly filmed while V is still serving in the military, making the surprise cameo even more meaningful. Though it wasn’t a full appearance, fans are already hoping for a proper guest feature once V completes his service.
