MemoriesBabylon

A legal drama starring Lee Joon-gi.
A free-spirited lawyer who refuses to be boxed in teams up with a passionate heroine attorney to fight for justice.
There’s a romance element, but it also blends suspense, action, and even comedy, making it incredibly engaging.
“Memories” conveys how the two leads truly connect and sing about being the best partners.
Beautiful MomentK.will

An insert song from a romance drama starring Lee Min-ki.
The heroine is an actress who plays a different face every week each month.
The hero has had a condition for over a year that prevents him from distinguishing people’s faces.
The protagonists stand out for their slightly unusual setup.
In this beautiful love ballad, the protagonist who can’t remember faces tries to recall just one woman.
Romance dramas involving memory are usually heartbreaking, aren’t they?
Heavenly fateLEE CHANGSUB

A gem-like ballad sung by Lee Changsub, the lead vocalist of the popular Korean idol group BTOB.
Released in February 2024 as part of the OST for the webtoon “A Not So Fairy Tale,” it explores the themes of parting and the enduring nature of love, conveying heartfelt emotions for someone dear.
The tense interplay of strings and guitar is layered with Lee Changsub’s emotive vocals, resulting in a track that resonates deeply.
His matured vocal prowess also shines as he marks the 12th anniversary of BTOB’s debut.
It’s the perfect song for healing the pain of heartbreak or reaffirming your feelings for someone special.
The WayOmuji

This song is sung by Umji from GFRIEND and is the theme song for the drama Shopping King Louie.
It features the cute, GFRIEND-like vocals.
The drama itself is adorable, and both the actors and actresses are charming, making this a perfect insert song that suits the show very well.
Just StayHyolyn

Shin Hye-sun and younger-actor type Yang Se-jong starred in it.
It’s a love story between a heroine who lost consciousness at 17 and woke up at 30, and a young man who has closed himself off from the world.
“Just Stay” sings about the romance between two people who are 30 years old yet as pure as teenagers.
You can’t help but feel your heart flutter as these two, each bearing their own wounds, sometimes clash yet grow closer.
It would be wonderful to experience a straightforward, school-days kind of love even at an adult age.
Fire GazingKyoung Seo

This is a song released in August 2024 by the Korean singer-songwriter Kyungseo.
It appears as the sixth track in the OST for the drama “Is It a Coincidence?”.
It’s a ballad marked by a sentimental, gentle melody and poignant lyrics.
The theme reflects on past memories and emotions, portraying the feeling of gazing at a campfire while facing old photographs.
Kyungseo’s delicate, emotionally rich vocals further enhance the song’s atmosphere.
Coupled with the drama’s memorable scenes, this track resonates deeply with viewers.
It’s a song perfect for quiet nights or moments of contemplation.
FutureRed Velvet

Songs that play during memorable scenes really stick with you, don’t they? With that in mind, I’d like to introduce “Future.” It’s part of the OST for the drama “Start-Up,” performed by the girl group Red Velvet.
I’ll avoid spoilers, but this song plays at the end of episode 1.
Their clear, pure vocals and the lyrics—which mirror the characters’ feelings—are truly moving.
It’s also a great recommendation if you’re looking for something refreshing or an uplifting anthem.
Love is like rainchangun soku

This is the OST from the romance drama Love Rain, starring actor Jang Keun-suk and Girls’ Generation’s Yoona.
Since Jang Keun-suk himself appears in it, it feels like the characters and emotions from the drama overlap even more.
In the chorus, true to the title Love Rain, the lyrics include sound effects like the gentle patter of rain and the thumping of one’s heartbeat, making it a rhythmically engaging song.
Christmas TreeV

Starring Choi Woo-shik and Kim Da-mi, this romance drama, Our Beloved Summer, about former lovers who never wanted to meet again, features this song in Part 5.
Sung by V of BTS, known for his overwhelming charisma and beauty, the track expresses how love deepens as each small moment accumulates.
Listening to it makes you want to convey your honest feelings.
With its sparse, graceful arrangement and V’s sultry vocals, it envelops you in both poignancy and powerful emotion.
smoothlyI he in

In a word, this song is adorable.
The singer’s voice is both girlish and like that of a beautiful grown woman—so pure that I could listen to it forever.
The lyrics tell of a man who somehow slipped into her heart and dyed her in his colors.
But she loves the version of herself colored by him.
The cute lyrics are part of the song’s charm.
