The title is ironic, and the lyric “Tonight, I’ll be the happiest girl in the world” reveals that it’s a song about being dumped by someone you love.

Set in a dreamlike world, the song wanders in search of love and a time we can’t return to.

Based on EDM, ATEEZ’s signature sexiness and energetic performance amplify those helpless, pent-up feelings, making it all the more heartrending.

It’s about being unable to let go of a love that has ended.

When we think of sad songs, ballads often come to mind, but this style that lets emotions explode is a unique charm of boy groups, don’t you think?

The Moment My HeartBoramiyu

Singer-songwriter Boramiyu, who has gained support on YouTube for her cover videos and their clear, translucent tone, has released a single on December 21, 2025.

It’s a remake of the beloved ballad that Kyuhyun sang in 2020 as part of the OST for the webtoon “취향저격 그녀 (She is My Type).” The song captures the trembling heart just before confessing feelings to a crush, carried by delicate piano and string melodies.

Boramiyu’s conversational vocal delivery brings out a fresh, innocent charm distinct from the original.

With a warm sound that seems to melt into the crisp winter air, it’s sure to gently encourage anyone feeling timid about love.

It’s also perfect for listening alone on a quiet night.

It’s an emotional ballad that seems to warmly envelop fans’ ears.

After a breakup, it conveys the sorrowful feeling of never forgetting the affectionate moments shared.

It’s alright This is LoveDavichi

Don’t you ever feel a bittersweet ache when you fall in love? That’s why I’d like to introduce “It’s Alright This Is Love.” It’s a piece by the musical duo Davichi.

The lyrics are woven from repeated self-questioning: What does it mean to love someone? Why does it make your chest tighten? Give it a listen and let your mind wander through the reasons for those feelings.

You’ll also be soothed by the piano’s timbre and their crystal-clear vocals.

EPIK HIGH (에픽하이) – 술이 달다 (LOVEDRUNK) ft. CRUSH [Official MV]
LOVEDRUNKEpik High, Crush

Is it a pun? LOVED, DRUNK—that is, a love song about alcohol, with the Japanese title “Sake ga Amai” (literally, “The Liquor Is Sweet”).

It sounds cool and understated, but the content is about a girl trying to forget a heartbreak with alcohol, capturing her bittersweet feelings.

Many people have experienced being “unsteady on their feet” or having their “head spin,” but probably fewer have felt that way specifically because of a breakup.

The much-talked-about music video is unique and eye-catching, too.

The woman who appears is the singer IU—an artist even Gen Hoshino has his eye on—and in the video she’s fighting someone.

It’s likely a metaphor; perhaps it was difficult to directly depict the state of being drunk.
