A timeline of IU and BTS' Taehyung's friendship: From music video co-stars to concert support

In January 2024, BTS’ Taehyung co-starred in IU’s music video Love Wins All. The video, set in a ruined futuristic world, portrayed the two as partners trying to survive. Their on-screen pairing drew significant attention across streaming platforms and online forums. Afterward, on January 29, BTS’ official YouTube page uploaded exclusive behind the scenes clips from the filming.

The footage captured the duo in a lighter mood, laughing during breaks. V shared that he had warmed up his voice in the car before filming, while IU jokingly disagreed, saying that wasn’t the reason his voice was strained.

They also ended up talking about their MBTI types, laughing as they debated who prepared more. Their casual equation had earlier been noted when Taehyung joined IU on her talk show, Palette.

The pair chatted with ease, as Taehyung informally addressed her as "noona," a polite Korean word for an older woman. Then, on September 22, 2024, the Winter Bear singer was seen attending IU’s conclusive Seoul concert, held at the Seoul World Cup Stadium.

This marked the closing night of the Korean leg of her HEREH world tour. Despite being enlisted, V took a brief leave to attend the show.
