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 refreshing and cheerful unrequited-love Vocaloid song.

With everyday words sprinkled throughout and the feelings of a girl with a crush expressed so straightforwardly, it leaves you with a very bittersweet sensation as you listen.

The brisk rhythm and guitar sound are wonderful.

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.

This is a song that depicts the kind of regret that makes you think things might have changed if you had only taken a small step forward.

Someone you thought you could stay with has gone somewhere out of reach, and you’re hiding your regret… Those feelings are expressed in concrete detail throughout the lyrics.

Depending on the person, it may feel extremely painful.

It’s a song often associated with cover singers, but the original has a beautiful chorus too, so I really hope you’ll give it a listen! It’s a track that can move you to tears with the contrast between its bright moments and its poignant ones.

The lyrics evoke an image like Orihime and Hikoboshi—wanting to meet but not being able to as they wish—singing of a love that’s sweet yet painful.
