Accompanist / Piano Instructoryuri
Accompanist pianist × piano instructor × web writer. I began piano lessons at age four and, inspired by my piano teacher, decided to pursue music. I went on to specialized music programs in high school and university, where I discovered the appeal of accompanying instrumentalists and singers. Currently, alongside teaching piano, I work mainly in my home region of Aichi as an accompanist for flute, voice, choir, and more. Through lessons, my students often introduce me to trending songs, and my hobby is trying anything on the piano—Japanese and Western pop, commercial jingles, and beyond. Since 2021, I’ve also been active as a web writer, covering music and a variety of other genres.

“The person I fell for already liked someone else.” “After I fell for them, I realized they had a girlfriend.” “I’ve fallen for someone else…”—that’s what my partner told me.

We’ve gathered love songs for those painful moments.

It’s heartbreaking when your feelings are growing, only for the love to become unrequited in an instant.

You can’t confess; even if you did, there’s no hope.

And yet, it’s too late to forget…

Here are some love songs recommended just for you.

“It hurts, but I can’t tell anyone.” When you feel like that, please give these a listen.

Bittersweet love songs to listen to when the person you like already has a boyfriend or girlfriend (41–50)

REN 'My Friend’s Lover Is My Ex' Official Music Video

My friend's lover is the person I used to date.Ren

This song poignantly portrays the bittersweet situation of your friend’s partner being your own ex.

REN’s powerful vocals and straightforward lyrics truly resonate.

Released in January 2024, it lays bare the complexities of romantic feelings.

While wishing for a friend’s happiness, the pain of resurfacing memories is heartbreaking.

You can really feel the struggle between the honest wish—“I want them to break up more than I want them to be happy”—and the conflict it causes.

It’s a perfect track for anyone troubled by love or burdened with complicated emotions.

A piercing piece that lets you fully experience REN’s unique world.

When the person you like already has a boyfriend or girlfriend... bittersweet love songs you want to listen to (51–60)

I hate iterica

erica – “I Hate You” PV Full

I hate iterica

It’s a bittersweet love song with a mid-tempo ballad feel.

Even though I’m in love, my feelings don’t reach them—maybe because I don’t like myself.

I’m sure that’s not really the reason, but unreturned feelings are painful, aren’t they? Especially when the other person finds someone they like—there’s no heartbreak like it.

Still, let’s believe that if we keep holding on, our feelings will eventually get through.

I highly recommend this song.

Even when it’s an impossible love because the other person is already taken, you can’t help thinking “why?” and find it hard to accept—that’s what being in love is like.

In the song “Koi,” Okuhanako’s vocals, set against a piano backdrop, sound in unison with those honest feelings of love.

Listening to a song like this makes you wish that every love could be rewarded.

Feeling in loveNishino Kana

Kana Nishino 'Feelings of Love' MV Full

Feeling in loveNishino Kana

A love song by Kana Nishino that portrays the struggles of two people who are more than friends but not quite lovers.

The secret feelings harbored for a longtime best friend are expressed with heartrending delicacy.

Even when the mind has given up, the heart can’t help but hold onto a faint hope—an emotion anyone who’s experienced unrequited love can relate to.

Featured on the album “with LOVE,” this track was released in November 2014 and captured the hearts of many listeners.

It’s a must-listen for anyone wavering between friendship and romance.

DREAMS COME TRUE – “If It Were Snow”

If It SnowsDREAMS COME TRUE

When it comes to Christmas songs, many are exciting and happy, but “Moshimo Yuki Nara” by DREAMS COME TRUE is a very bittersweet Christmas song.

It expresses the negative feelings of unrequited love.

The honest emotions are laid bare, which makes the heartbreak feel even more intense than in other songs about unrequited love.

Kana Nishino 'Have a nice day' MV (Short Ver.)

Have a nice dayNishino Kana

Rather than a peppy love song, it feels more like a cheer-up anthem for yourself.

“The person I like already had a boyfriend” pops up just for a moment, but it’s a wonderful track filled with positive words that lift the listener’s spirits.

When you feel like you’re about to lose in the struggles of everyday life or when you’re feeling down, this song is highly recommended.

It will surely make you feel better.

A love with you, separated by nineSHIROSE from WHITE JAM

I turned the LINE message I sent to my lover directly into a song. “A Love With You, Nine Years Apart” SHIROSE from WHITE JAM [Live Video]

A love with you, separated by nineSHIROSE from WHITE JAM

A masterpiece that turns an actual LINE conversation into a song.

These days, romance can develop over social media without ever meeting face-to-face.

I feel like genderless relationships, where age and gender don’t matter, will become the norm.

Being able to type out a long message on LINE is something you can only do when you truly care.

It’s a recommended track for those who are in a social media romance.
