“NINETEEN” is an upbeat pop-rock track showcasing the members’ bass, guitar, drum, and keyboard skills. The song incorporates several Japanese lines showcasing Hagiwa and Keiten’s diverse cultural backgrounds.





未来が不安になる時も
Be mine, 다 다 다 다른 곳에 있어도
너만을 향한 맘은 여전해
순수한 모습 그대로





The lyrics serve as a love letter to a past relationship, empathizing their undying affection despite separation. Through hardship and sudden changes, the narrator returns to the love that still makes their heart flutter, a love that remains certain when life isn’t.

Cause all you gotta do, ooh, ooh, ooh
Is hold me like we used to, ooh, ooh
The youth we thought would last forever, ooh, ooh, ooh
Forever, forever like nineteen

The narrator expresses through heartfelt lyrics that fill the song with a nostalgic warmth. Despite growing older, reminiscing or being reunited with a past love brings back the same rush of emotions, making them feel nineteen again.

The accompanying music video captures the aching and longing for love that now feels unrequited. The members of hrtz.wav are shown engaging in youthful mischief, sneaking into buildings, and racing away from security. A fun montage follows of YOUNYOUNGJUN, RIAAN, DANE, KEITEN, and HAGIWA scavenging through and trying on various clothes.

The carefree adventures mirror the same nostalgic youth and warmth expressed throughout the lyrics, ending with the boys staring at the sunrise together.
