Girl group Afuture will make a comeback on the 21st with their new song 'Last Party' alongside new member Nayeon.

Their agency, 4by4 Creative, announced on the 9th that Afuture will release 'Last Party' that day.

The song was produced again by composer Jin Dae-ho, who worked on their previous song 'Spring Shower.' It was also co-produced with singer Soonsoonhui's 'Mirrorball,' emphasizing Afuture's unique sensibility and musical color.

Despite its title, 'Last Party' is a song themed on a new beginning rather than an ending. It carries a message of leaving the past behind and announcing a fresh start, which naturally connects to Afuture's recent member change.

Afuture debuted in March as a project girl group formed through the YouTube channel '4X4CREW.' Within a month of their debut, they performed at numerous events at home and abroad, and have been steadily active at military bases and related events across the country.

Meanwhile, member Ire recently left the group for health reasons, and Nayeon joined as a new member.

Afuture's new song 'Last Party' will be released on various music platforms on the 21st.
