2F's Kim Won-joo Releases Emotional Ballad for 'Love Prescription' OST Today

2F vocalist Kim Won-joo releases her first OST contribution to KBS 2TV's 'Love Prescription' today, the 12th, at 6 p.m. KST. The sixth official soundtrack for the weekend drama, titled 'That's Only You' ('그대뿐이죠'), is a lyrical ballad that channels deep longing and heartfelt emotion.

The track centers on unchanging love and the cherished memories that sustain a relationship through frozen time. Won-joo's warm delivery brings these sentiments to life, layering her steady, nuanced vocal expression over evolving melodies and lush arrangements. The production is designed to deepen viewer immersion as the drama unfolds.

The lyrics underscore this emotional resonance: "You are the only one in this world, and because I dream of you today, I hope I can smile. Every day has shined, and every day is precious." This sincerity elevates the track's emotional stakes.

The entire 'Love Prescription' soundtrack is helmed by Song Dong-wun, one of South Korea's most accomplished OST producers. Song has overseen soundtracks for acclaimed dramas including Goblin (which spawned hits like 'First Snow' and 'Stay With Me'), Descendants of the Sun, It's Okay, That's Love, Scarlet Heart: Ryeo, and Our Blues, establishing a track record of memorable, chart-friendly compositions.

'Love Prescription' is a family drama about two households bound by misunderstandings for 30 years. The narrative follows their journey as they resolve conflict, heal each other's wounds, and ultimately rebuild themselves as one family. The series airs Saturdays and Sundays at 8 p.m. on KBS 2TV.

'That's Only You' is available now on all major Korean music streaming platforms.
