The lyric music video teaser for the new Nexstar Project song "Between Us Called Friends, So Heartbreaking," featuring singer Kassy, was released on the official Nexstar Entertainment YouTube channel on the 10th. The new song will be officially released on various online music platforms at 6 PM on the 15th.

The released teaser video begins with a scene of a red heart slowly rising under a quiet night sky. The video includes part of the lyrics: "At some point, I fell in love with you / I can't hide this overwhelming heart / Even if I can never live like before again / I will confess to you that I love you." This visually expresses the emotional line of the song, which captures the bittersweet feelings of being "more than friends, less than lovers."

"Between Us Called Friends, So Heartbreaking" is a ballad confessing a heart that is too afraid to call it love but can no longer be hidden. The composition and arrangement were handled by Jo Young-soo, with Kassy co-writing the lyrics to enhance the song's completeness. Kassy's clear vocal tone layered over warm acoustic sounds maximizes the song's overall lyricism.

Jo Young-soo is a representative composer who has led the era of Korean emotional ballads, working with many artists such as SG Wannabe, Davichi, and SeeYa. Kassy is a beloved vocalist known for songs like "Those Days Were Good" and "A Song Filled with Sincerity," drawing listeners' empathy through honest lyrics and delicate expression.

Immediately after the official video release, fans responded with comments such as, "My heart dropped from the first verse," "Each line is so realistic that it draws me in more," and "The chemistry between the two is still perfect."

This song, presented by the two artists reuniting, is a ballad that delicately follows the texture of emotions. Ahead of its official release on the 15th, the new Nexstar Project song "Between Us Called Friends, So Heartbreaking," created by Kassy and Jo Young-soo, is expected to add warmth to listeners' playlists.
