Jin, a member of BTS, recently released the second single "Running Wild" from his debut solo album Happy on November 15, 2024. The song embraces themes of embracing impermanence and finding joy in life’s simple pleasures. The music video, which was previewed in a teaser, showcases Jin spending time with his dog and enjoying carefree moments such as running along the road and sharing intimate moments, even as a sense of impending end looms in the background.

The track carries a message of living fully in the moment, even in difficult circumstances. The lyrics, “We'll be running wild, loving ‘til the Sun is out,” reflect this embrace of living with abandon.
