Leiayuyoyuppe

It’s a slightly abnormal track.
The aggressive rock sound is striking above all.
The lyrics, which evoke the image of dragging something beautiful down with your own hands, really hit home.
Recommended for those who want something with a different vibe from a pure love song.
15 Years of a Clingy Guy’s Petty ObsessionIe no ura de manbō ga shinderu P

As the title suggests, you’ll be led to believe it’s just a slightly creepy song about unrequited love—if only that were true.
The way the words are woven in, almost like a gag, is sure to make you laugh.
However, by the middle of the song, anyone perceptive will realize what it’s really about.
This track, which passionately sings of unwavering devotion, is one you should definitely listen to all the way to the end.
milk teadada

Love at first sight, and an unrequited love that stayed that way.
It’s a cute yet bittersweet song about a relationship that would make anyone watching feel impatient.
Though it began with love at first sight and no connection between them, everything started from a cup of milk tea.
The happy days that followed for the two warm our hearts as we watch them.
And it’s milk tea again that brings back those days that have now slipped into the past.
It’s a song that takes our emotions for a spin.
A single-hearted unrequited love, a small happiness I want to make come true.utatata P

This is a song by Utata-P, a Vocaloid producer also known for works like “Stratosphere.” It was released in 2012, with lyrics written by Hitsuji Torii.
The piece calls to mind one of Utata-P’s popular tracks, “This Is the Happiness and Peace of Mind Committee,” featuring an enormous gap between the title, the musical style, and the lyrics.
It might be hard to imagine, but it’s a stalker-like unrequited love song.
“Single-minded devotion” can be a tricky thing, can’t it? Please take your time and listen to this cleverly perspective-shifting love song.
Dyed in watercolormisumi

A bright and cute Hatsune Miku song.
It features lyrics with a summery freshness—soft and translucent like watercolor—and a buoyant, bouncy melody.
It’s a track you’ll want to listen to when you want to be single-minded in love, imagining the person you like right by your side.
adolescent boys and girlssunatsubu

This is a song about a love triangle that can’t be spoken aloud.
Despite a theme that could easily turn messy and dark, it reaches us with a refreshing rock sound.
The melody itself is pleasantly easy on the ears, yet beyond that, a boundless, aching, helpless emotion comes flooding in.
It’s a track that reveals even the painful and troublesome sides of love.
Sullen WaltzOSTER project

A delightful yet slightly bittersweet classic set to a lively waltz rhythm, capturing the tang of unrequited love.
Created by OSTER and released in 2008, it features striking lyrics that liken clumsy feelings of love to glass marbles.
The inability to speak smoothly with the one you like, the struggle to be honest—those emotions come through in Hatsune Miku’s voice.
The pop, catchy melody is wonderfully comfortable to listen to.
It’s a must-listen not only for those in the midst of a crush right now, but also for anyone who wants to bask in a sense of nostalgia.
