A glimpse into the special collaboration stage between BTS's Jin and Coldplay has been unveiled.

Coldplay shared rehearsal photos featuring Jin on their official social media on April 20. The images depicted Jin rehearsing 'My Universe' and 'The Astronaut' with Coldplay's Chris Martin.

In the revealed photos, Chris Martin and Jin could be seen practicing their stage performance in the rain. Despite the rain, both artists, with Jin wearing a raincoat, rehearsed energetically, showcasing their dedicated passion.

During their return to the main stage, Chris Martin showed warmth by wrapping his arm around Jin's shoulder. A picture captured Jin holding a banner towards Chris Martin with determination.

Jin surprised the audience by appearing during Coldplay's concert at the Goyang Sports Complex on April 19. He joined Chris Martin on stage during the "Songbook" segment, where audience members were invited to sing along. Jin held a banner asking to perform 'The Astronaut' with Chris Martin, which led to him being called on stage.

Upon Jin's appearance, Chris Martin knelt down, and Jin reciprocated the gesture, displaying their strong bond. Together, they performed 'My Universe'.

'The Astronaut' is Jin's solo debut song, co-written and composed by Coldplay, which garnered considerable attention. The collaboration between BTS and Coldplay on 'My Universe' was well-received, and during the concert, holograms of BTS members serving in the military were displayed on the LED screens.

Chris Martin expressed his fondness for BTS members directly, demonstrating his ongoing support for the group.
