[talk] Have you seen Coldplay's concert in Korea? BTS Jin makes a surprise appearance holding a placard! A touching joint stage!

Chris Martin had a moment during the show where he invited an audience member on stage, and Gene was holding a placard that said, "Would you like to sing 'The Astronaut' with me? Pick me."

This could have been a pre-planned surprise event, or it could have been something that happened spontaneously on the spot. Either way, it was possible because of Coldplay and Jin's close relationship.

In conclusion, BTS' Jin's appearance at Coldplay's concert was a touching moment that combined several factors: the deep friendship between the two groups, Jin's first official appearance since his military service, and a special gift for fans.
