Hearts2Hearts are set to return with a touch of romance. The group will release their first mini album "FOCUS" on October 20, and on the 14th, they unveiled a concept teaser along with a preview of the track "Flutter."

A Soft and Romantic City Pop Sound
"Flutter" belongs to the city pop genre, blending strings, brass, and keyboard sounds in perfect harmony. The group's smooth vocals and rich harmonies create a warm, romantic atmosphere that captures Hearts2Hearts' signature tone.

The lyrics tell the story of someone taking the first step toward a hesitant lover — a confession filled with anticipation and emotion. The song fully embraces the group's delicate and sentimental style.

Kenzi and KZLAB Behind the Music

The track was written and composed by Kenzi, with Andrew Choi and the producing team KZLAB joining in. According to SM Entertainment, "Kenzi also wrote the lyrics for the title track 'FOCUS,' so fans can expect strong synergy across the album."

Teaser images released the same day feature Hearts2Hearts standing in a symmetrical composition centered around light blue tones and heart-shaped objects, radiating a fresh and dreamy charm.

The upcoming mini album "FOCUS" includes six tracks in total and will be released on October 20 at 6 p.m. KST across major music platforms.
