It’s a sad breakup song that can be heard as either a song about an affair or about having a brief relationship with someone you shouldn’t fall for.

Released in 2020 as aiko’s 39th single, it has a relatively bright sound, but the lyrics are heartbreakingly poignant.

For those who are in a love they can’t tell anyone about and are desperately holding themselves back to keep the relationship from ending, it will be painful to listen to—but it will surely stay by your side, too.

Give it a listen when time alone feels lonely or empty.

A legendary ballad in the history of Japanese pop, covered by numerous famous musicians.

There’s a saying, “The one who falls in love loses.” The one who falls in love is the one who always bends, steps back, endures… ends up forgiving everything—even forgiving it when the person they love falls for someone else.

Does that mean such a person isn’t allowed to love at all? That can’t be true.

It might be a common tale of romance, but every line of this song’s lyrics is packed with the aching tenderness of love.

Beware: if you’re heartbroken, you might not be able to stop the tears when you listen.
