The repeated phrases leave a strong impression, and the atmosphere blends sweetness with bittersweet longing.

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.
PromiseDOYOUNG
A heartfelt ballad by Doyoung, the main vocalist of NCT.
It was released as the title track of the single album “Promise” in December 2025.
After establishing his presence as a solo artist with his first album “YOUTH” in 2024, he also took part in writing the lyrics this time, expressing gratitude to someone precious and a vow of unwavering love.
The structure is very dramatic, beginning with a gentle piano melody and gradually expanding into grand strings.
Given that it was released the day after his enlistment, it also resonates like a sincere letter to his fans.
It’s a song I highly recommend when you want to feel connected at heart despite the distance, or when you’d like to be soothed by an earnest, genuine vocal performance.
You won’t forget meKIM CHAEHYUN
Kim Chaehyun, who enchants as Kep1er’s main vocalist with her clear, crystalline voice.
This work, released in December 2025 as her first solo single, showcases a different side from her group activities and lets her individuality shine.
It’s a ballad built on a band sound, carefully conveying the complex emotions that linger after a breakup—feelings of loss and lingering attachment.
Chaehyun’s delicate yet resolute vocals draw you in, expressing a heart-wrenching poignancy.
Produced as part of a collaborative project involving Dreamus Company and others, it also sparked buzz with behind-the-scenes footage revealing the recording process.
It’s a track that seems to melt into the cold air of winter, best enjoyed alone on a quiet night.
Solar SystemKIM SEJEONG
Kim Sejeong, who first rose to fame as a member of gugudan and is now beloved for both her acting and singing, released the single album “Solar System” in December 2025—a work that deeply resonates with the sensibilities of winter.
This release is a remake of one of Sung Si-kyung’s signature ballads, arranged by guitarist Jeok Jae, who breathes new life into the piece while preserving the lyricism of the original.
The lyrics poignantly liken the habits that linger after a breakup to the orbits of planets revolving around the sun.
With restrained, acoustic production, the sound blends seamlessly with her delicate vocals, echoing like an intimate soliloquy.
It’s a song that will gently accompany quiet nights spent alone in contemplation.

If you want to savor a sharp allure hidden within sweetness, be sure to check out the multinational girl group SECRET NUMBER! Their digital single “Bitter Sweet,” released in December 2025, is a high-end hip-hop track driven by heavy drums and a resonant bassline.
Dropped after a major milestone—the group’s 2025 member reorganization—the song features contributions from creators like Opius and Na Doyeon, and stands out with an addictive hook.
True to its title, it portrays a duality of sweetness and bittersweetness, while highlighting a provocative, confident stance that defies the other party’s expectations.
It’s the kind of track that mysteriously empowers you when you want to feel confident or stay true to yourself.
Please don’t go and get happy, okay? (mwah…)UNIS
UNIS is a girl group formed through the audition program “UNIVERSE TICKET.” Released in December 2025, this work is their second Japanese digital single, which drew attention for being written and composed by Japanese singer-songwriter Koresawa.
The arrangement was handled by TeddyLoid and Carlos K., and the lyrics are striking for portraying emotions like jealousy and possessiveness as a cute sense of “mischief.” Motifs suggesting blown kisses are sprinkled throughout, wrapping listeners in a sweet kind of restraint.
It’s also noteworthy that the choreography was created by Hana, the winner of Street Woman Fighter.
This charming track is one you’ll want to listen to when your feelings of love are swelling or when you want to bring out your cutest self.
