Its theme is steadfast love that never fades, no matter how far apart you are—even transcending time.

A song by Ruki Kitaya that delicately portrays lingering attachment and bittersweetness after a love has ended.

The protagonist’s emotions, as they try over and over in dreams to start again, are deeply moving.

Their search for the reason behind the “change of heart,” and the inability to forget the final moment, come across almost painfully.

Released in January 2023, this piece showcases the depth of Kitaya’s musicality.

While holding the pain of heartbreak, it gently encourages those who are trying to move forward.

It’s a song I especially recommend to anyone who has just gone through a breakup or is feeling the loneliness of losing someone important.

Ren – Can't Bring Myself to Hate You (Music Video)

It’s a heartbreak song filled with the bittersweet feeling of not being able to hate the person you love.

You can’t get them to look your way, yet you can’t forget them… Anyone who’s been through that will surely relate.

In this piece, lingering attachment and affection for the other person are expressed plainly.

It also portrays the self-loathing of wishing they’d say they love you—even if it’s a lie—tightening your chest with emotion.

It’s a recommended track for when you want to soothe the pain of heartbreak or when you’re struggling to be honest about your feelings.

It’s back number’s song that gently embraces such bittersweet emotions.

Memories with someone important may one day fade away.

Even so, it conveys the desire to cherish each and every moment.

For those whose heartbreak has yet to heal, this is a song that quietly stays by your side.

Why not surrender yourself to it while holding close the feelings you keep in your heart?
