Set to a heartrending melody, feelings of farewell are sung.

Released in 2018 as a song by Kanzaki Iori and later included on the album “Hakushi,” it poignantly voices regret over a past romance and emotions for days that can never return.

The piano-centered arrangement unfolds dramatically toward the latter half, making it feel as though every note carries emotion.

A track by pinoko whose vocals and beats melt pleasantly into your ears.

It’s the title song from the EP “Little Devil EP,” released in October 2019.

The theme is the sweet yet slightly precarious push-and-pull found in the small moments of everyday life with a lover.

You can picture the intimate scenes unique to close relationships: a languid figure sipping morning coffee, or the gesture of hiding a token of affection.

As you listen, you can almost feel the warmth of that life.

Put it on during your downtime, and you’ll sense your tired heart gently unwind.

The struggle against the unintended “label” of individuality, distilled into the lyrics, invites deep empathy from listeners.

For those troubled by their complexes or overly concerned with others’ eyes, this will resonate profoundly.
