Singer-songwriter Paul Kim will officially release the BGM of 'Jung Hae In's Travel Log' (also known as 'Jung Hae In's Walking Report') after 4 years.

"One At A Time" is a ballad song written and composed by Paul Kim himself. It was used as the background music for KBS 2TV's 'Jung Hae In's Travel Log', which aired in 2019. Since then, the official release has been confirmed due to the constant requests from music fans.

In particular, Paul Kim recreated "One At A Time" with a vibe suitable for early spring. Paul Kim's sweet voice on top of the melody arranged with strings leads his careful lyrics to be the center of focus. Paul Kim's long-awaited ballad is expected to excite listeners.

Along with the song, the music video for "One At A Time" will also be released. Paul Kim's vocals will be combined with emotional visuals to give fans the pleasure of watching and listening.

"One At A Time" will be released on February 23 at 6 PM KST through various online music sites.
