Jin made his much-anticipated return to television through tvN’s Handsome Guys, which premiered on May 15 (KST). The BTS vocalist joined regular cast members Kim Dong-hyun, Lee Yi-kyung, Oh Sang Wook, Cha Tae-hyun, and Shin Seung-ho on a food recommendation tour around Seoul’s Hannam-dong.During the show, Jin was asked which Bangtan members would best fit the show’s energy. Without hesitation, he named Jungkook, explaining that he "really eats well.” When Oh Sang-wook, a 96-liner, asked about V and Jungkook’s ages and realized Jungkook was younger, he joked that Jungkook could appear as his junior. Jin then jumped in, saying he wouldn’t dare talk down to Jungkook because of the idol’s “scary” fans.A month later, on June 13, Jin and JK surprised fans with an emotional reunion at j-hope final concert of his HOPE ON THE STAGE world tour in Goyang, Gyeonggi. Jungkook made a surprise appearance during the performance of i wonder..., a Hobi track featuring his vocals. Recently, Jungkook updated his Instagram @mnijungkook with new music picks, sharing I Can’t Breathe by Bea Miller, In My Head by Peter Manos, Cool by Daniel Caesar, and Apollo Eighteen by Khamari. The 28-year-old, who’s stayed mostly inactive online since BTS began military service in late 2023, posted the emotional ballads and R&B tracks in early morning UTC hours.
