Group BTS Jin unveiled the last concept photo of Solo single. Jin, who is set to release his Solo single "The Astronaut" on the 28th, posted a full shot and a Close-Up shot of his last concept photo "Land on Earth" on BTS' official SNS on the 26th. This photo has a warmer color than the previous 'Outlander' and 'Lunar Eclipse' versions, creating a fairy tale atmosphere. In the 'Land on Earth' version concept photo, Jean boasted a boyish visual with a firm hairstyle and freckle makeup. The full shot has a sense of 'global' atmosphere that is unfamiliar to astronauts through the harmony of various props and backgrounds, and in the Close-Up shot, Jean is making a dreamy look that seems to fall straight. Jean has demonstrated a wide range of digestive power through three versions of concept photos 'Outlander', 'Lunar Eclipse' and 'Land on Earth'. Jean, who has released the concept photo, will release the music video teaser of 'The Astronaut' on the 27th. On the other hand, Jean will participate as a special guest in the Argentine performance of Coldplay World Tour 'MUSIC of the SPHERES' on 28th (local time) and perform 'The Astronaut' with Coldplay.
