BTS's Jin returned to Korea after performing his solo single 'The Astronaut' at the Coldplay concert.

He arrived at the Incheon International Airport on October 31 after finishing his schedule in Argentina. On this day, he was seen wearing casual clothing and waving his hand at the reporters.

Earlier, Jin headed to Buenos Aires, Argentina, on October 28 to perform at Coldplay's world tour 'MUSIC of the SPHERES' and showed off the performance of 'The Astronaut' for the first time on the day of release. 

The Astronaut' is an impressive song with a calm acoustic guitar in the pop rock genre and a synth sound that gradually rises. Jin participated in the writing of the lyrics to 'The Astronaut,' which contains the message expressing Jin's love for ARMY (BTS fandom).

Meanwhile, Jin is expected to start preparing for military service. In regards to this, Big Hit Music said on October 17, "We would like to inform you that BTS has begun detailed preparations to fulfill their military service obligations. Member Jin, who will soon have a personal activity, plans to apply for cancellation of enlistment at the end of October. We will follow the enlistment-related procedures of the Military Manpower Administration. The other members will also perform their military service sequentially according to their plans.”
