The piece explores themes of pain and dependency, portraying a protagonist who suffers in relationships with others while questioning their own reason for existence.

Haruna. “Don’t mess with me.” feat. Hatsune Miku

This is a track by Haruna, included on the album “Summer Sky Free Notebook: Page 1,” released in May 2023.

Its emotional, fast-paced rock sound and lyrics filled with anger, sorrow, and an unforgettable ache toward a former lover really strike a chord.

Every down-to-earth word lined up there is so relatable.

I highly recommend it to anyone who needs time to face the pain of a breakup.

Sad, sad, palm of my hand. / A Cold

It’s a translucent, shimmering pop song that gently touches the sorrow hidden in the heart.

Created by the Vocaloid producer kyiku, it was released in September 2025.

The track portrays a protagonist who carries a sense of isolation—as if cut off from the world—yet prays for their unchanging everyday life to continue.

That earnest longing tightens your chest before you know it.

The creator has said it’s “filled with feelings I want to cherish,” and you’ll find yourself deeply drawn into its world.

It’s the kind of song that seeps into your heart when you listen alone on a quiet, contemplative night.

Cannot Say / Hiragi feat. Hatsune Miku

It’s a pop tune that startles you with a bittersweet cry of the heart, in contrast to its stylish vibe.
