Pink Strawberry Chocolate Friday

Despite its poppy, sugary turns of phrase, this breakup song tightens your chest with a mature sense of loss and a mellow resonance.

Produced, written, and composed by Sho Hirano, it’s a solo track included on Number_i’s second full-length album, “No.

II,” released in September 2025.

Over a sophisticated sound where electronica and hip-hop intersect, it sings of the afterimages of a love that has ended and the earnest longing for the person who even appears in dreams.

While putting on a bright face yet harboring lingering feelings, this piece stays close to you in those moments when you suddenly feel lonely in the stillness of the night.

With a voice that’s disarmingly straightforward and tinged with fragility, it gently lifts up the overflowing emotions for the one you can’t forget.

Romeo and Juliet

This song starts with a cute-sounding intro, so compared to other Number_i tracks, it gives a different vibe.

The chorus is especially straightforward and is melodic rather than a rap.

The A section and rap parts are generally low—around A3 to E4, I think.

The highest notes go up to about D5, but low-voiced male singers don’t need to worry that it’s “too high to sing.” If you like rap styles, this is a track where you can enjoy both rap and melody, so definitely give it a listen!

The continuation of the dream

Number_i is drawing attention for their sophisticated dance performances and genre-defying musicality.

While many of their tracks lean heavily into hip-hop, this piece is perfect for those seeking a gentle sound that stays close to the heart.

It’s a ballad that closes out their mini-album “No.O -ring-,” released in May 2024, and is also known for being produced by Yuta Jinguji.

Its poignant world—overlaying rainy scenery with the continuation of a dream—quietly seeps into the listener’s heart.

The lingering aftertaste, deliberately placed at the very end of the album, is superb.

On a night when you want to forget the busyness of daily life and relax, take your time and really listen.
