Have you ever hated someone because you loved them too much? When love can’t be digested, it can turn into hatred, can’t it? Perhaps that just means the love was that immense.

Jongin’s “I Hate You” is a song that expresses the feelings of even experiencing hatred precisely because of love.

A collaborative number by B.I and Paul Blanco, who also teamed up on “Summer” in 2022.

Though it’s a breakup song that sings of lingering feelings, its straightforward, earnest message is relatable—even if you’re watching from a slight distance with a hazy gaze.

“If I fall in love again, I want it to be with you”—that special sentiment comes through.

The R&B-tinged track and the lyrics layered over music that feels almost autobiographical make it all the more heartrending, tightening your chest.

A bittersweet ballad released by BTOB in October 2024.

Blending a weighty band sound with the members’ voices, this is a track we especially recommend to anyone who has experienced heartbreak or parting.

A medium-tempo tune you’ll want to listen to absentmindedly when your heart feels cloudy or you’re not in the best mood.

Still, his gentle vocals wrap up the pain and offer comfort.

This is a song that blends the aching emotion of farewell with a warm sense of gratitude, resonating deeply with Hyunjin.

Formerly a member of LOONA and now active as part of Loossemble, she released this work in December 2024.

Set to an R&B-tinged melody, it quietly confesses the complex feelings that come after an unavoidable parting.

The beautiful music video, set against a winter backdrop, further enriches the song’s world.

It’s a recommended track for those times when you want to heal the pain of heartbreak or savor your gratitude for someone important.

Debuting in 2009 as a sister group to Girls’ Generation and gaining popularity in Japan as well, f(x) featured Luna as the main vocalist.

Her 2018 solo track “Night Reminiscin,” a duet with fellow Korean male singer Yang Da Il, drew attention for that collaboration too.

It’s a simple piano-based ballad, yet their beautiful voices and the melody overwhelm you with a flood of emotion—even if you don’t understand the lyrics.

The inner landscape of the protagonist, who spends night after night swaying with feelings for a loved one that will likely never reach them, is profoundly lonely and sorrowful.

If you’ve had similar experiences, be careful not to empathize so deeply that it becomes painful.
