[Korean Drama OSTs] Classic Popular Songs That Color the Story: Best Masterpieces

from now onKim Min-seon

김민승 Kim Min Seung – 앞으로 From now on (역도요정 김복주 OST PART 2) Official M/V

It’s an upbeat, fast-tempo song that plays during bright scenes in the drama, and it makes you want to start dancing.

The singer is male, but his voice is quite high for a man, so it’s surprising at first; still, his distinctive tone is addictive and makes you want to listen again and again.

Moonlight Drawn by CloudsGUMMY

[M/V] 구르미 그린 달빛(Moonlight Drawn by Clouds) (구르미 그린 달빛 OST) – 거미(Gummy)

It’s a quintessential ballad.

In the chorus, the woman’s beautiful high register carries on, and the delicate dynamics unique to a female voice—along with the subtle tremble—are gorgeous, heightening the drama’s tension.

The vocals themselves feel heartrending, and the lyrics are also poignant, making it a song you’ll want to listen to slowly.

When the Day ComesTOMORROW X TOGETHER

[언젠가는 슬기로울 전공의생활 OST Part 9] 투모로우바이투게더 (TOMORROW X TOGETHER) – 그날이 오면 (When the Day Comes) MV

A delicate song woven with the warm resonance of acoustic guitar, brimming with the bittersweetness and hope of youth.

TOMORROW X TOGETHER joins the OST for tvN’s drama “Someday, a Wise Resident Life.” Members Soobin and Yeonjun make cameo appearances in the series, adding sparkle to the much-talked-about scene where they perform as the fictional idol group “HI-BOYZ.” Since its release in May 2025, the song’s candid portrayal of pure young love and the members’ refreshing vocals have continued to captivate both drama fans and K-pop listeners.

A gem of a track, highly recommended for anyone seeking a fresh, pure love song.

Remember meGUMMY(거미)

Gummy(거미) – Remember Me(기억해줘요 내 모든 날과 그때를) (Sketchbook) | KBS WORLD TV 201127

In 2019, a major hit in South Korea was Hotel Del Luna, starring Lee Ji-eun—known as the nation’s little sister, IU—and Yeo Jin-goo.

Its OST was luxurious across the board and became a hot topic.

One of the songs features Komi singing about a heartrending love.

Her mid-range, husky voice makes the poignant lyrics even more dramatic.

Feelings that don’t reach the other person are truly frustrating and painful, aren’t they?

Say YesLoco, Punch

[달의 연인 – 보보경심 려 OST Part 2] 로꼬, 펀치 (Loco, Punch) – Say Yes MV

A track that combines a woman’s beautiful singing with a man’s rap.

The balance between the sung and rapped parts is exquisite: the woman’s vocals alone would make it a sorrowful song, but the man’s rap keeps it from becoming too melancholy, without turning it into a cheerful tune either.

It lands in just the right place.

Even if I die, it’s you.JIN,V

V (뷔) & JIN (진) [BTS] – 죽어도 너야 (Even If I Die, It’s You) [화랑 Hwarang OST Part.2]

This is a song by JIN, the oldest member of BTS, who are hugely popular in Korea right now, and V, who appeared in the drama where this song is the ending theme.

The song has a great tempo, and their cool voices match the drama perfectly.

It’s a track that really highlights how well the two sing, even though they usually perform as part of a large group.

Love, MaybeMeloMance

The romantic comedy drama Business Proposal, starring Ahn Hyo-seop and Kim Sejeong, who is also active as an artist, featured a self-cover by MeloMance of a song they originally provided to SECRET NUMBER, which they performed in the show.

The track became a huge hit and enjoyed a long run.

It’s a top-tier love song showcasing their highly acclaimed songwriting skills.

The relaxed vibe of the song is also adorably charming.

Packed with the fluttery excitement of love, this track is irresistibly romantic—paired with the drama, it’s guaranteed to make your heart skip a beat.

Japanese subtitles/Kanlubi/Karaoke lyrics [The Day We Met (A Day Like a Movie)] CHEEZE [Encounter (Boyfriend) OST Part 1]

When I listen with concentration, I can’t help but be drawn into a mysterious sensation.

In the A section, amid a bed of indistinct sounds, there are unexpected combinations like a piano briskly marking staccato.

In the chorus, suddenly emerging strings appear, and the unpredictable arrangement pulls the listener in even deeper.

[사랑의 불시착 OST Part 1] 10cm – 우연인 듯 운명 (But it’s Destiny) MV

Crash Landing on You, a mega-hit that sparked a major social phenomenon in Japan.

The song that plays from episode 1 has a title meaning “a fate that seems like coincidence,” symbolizing the two protagonists’ meeting.

The track was produced by 10cm, known for outstanding pop sensibilities and numerous hits, including OST work.

With Kwon Jung-yeol’s sweet vocals, the lyrics—conveying a generous, expansive love—truly resonate.

It’s perfect to enjoy alongside the drama, and also recommended for those moments when you want to relate it to your own experiences.

A wonderful love song that lets the thrill of the extraordinary blossom and spread in your heart.

[MV] JINHO(진호) (PENTAGON(펜타곤)), Rothy(로시) _ A little bit more(조금만 더) (김비서가 왜 그럴까 OST Part.4)

This magnificent ballad, elegantly woven with piano and strings, was released in June 2018 as part of the OST for the drama “What’s Wrong with Secretary Kim.” Jinho, the main vocalist of PENTAGON, delivers powerful high notes that blend beautifully with solo singer Rothy’s crystalline voice, delicately portraying the subtle emotions of two people newly in love.

The song was used in some of the drama’s most memorable scenes, gently narrating the protagonists’ inner feelings and resonating with many viewers.

It’s perfect not only for those harboring bittersweet feelings of love, but also as background music for cherished moments with someone special.
