Good-for-Nothing “Hastily, Without Formalities” / Rokudenashi – Sincerely Yours [Official Music Video]

Motifed after letter closings, this ballad calmly yet fervently paints emotions too vast to fully convey.

Sung by vocalist Ninjin as part of the next-generation music project Rokudenashi, the song was written, composed, and arranged by Vocaloid producer Kanzaki Iori.

It also gained attention as the theme for Episode 2 of the Amazon Original drama “Oshi no Ko,” released in November 2024.

The delicate emotional nuances that waver within a quiet soundscape, and the dramatic development that lets feelings overflow toward the latter half, are truly heart-wrenching.

The earnestness of thinking of someone with words that won’t come together may gently keep you company on sleepless nights when your feelings can’t be put into words.

Take your time and listen closely.

This song is a fast-paced love tune whose bright yet somehow bittersweet melody lingers in your chest.

It was released in June 2023 by Rokudenashi, a project featuring vocalist Ninjin.

Within its pop sound lies a subtle loneliness, vividly expressed by Ninjin’s clear, translucent voice, making your heart tighten a little more with every listen.

The track was later included on their first album, “Ai ni Saku Hana.” It’s perfect for those moments when you want to look up at the night sky and sink into a sentimental mood.

A masterpiece especially for anyone harboring secret feelings.
