He Wrote This Song 10 Years Ago Now Park Bo-gum & Jinyoung Are Singing It Together, and Giving The Money Away

Ten years ago, a soft-spoken historical romance about a crown prince and a cross-dressing eunuch quietly became a cultural touchstone. This week, two of the people who made it happen returned to close the loop. Actor Park Bo-gum and singer-actor Jinyoung have reunited to remake “Foggy Road” (안갯길), one of the most cherished tracks from the Moonlight Drawn by Clouds soundtrack and the reunion is far more meaningful than a simple nostalgia play, because Jinyoung wrote the original himself.

The remake dropped across Korean music platforms at 6 p.m. KST on September 23, timed to the drama’s 10th anniversary. And in a gesture that reframes the whole project, all proceeds from the release will be donated a way, as the artists put it, of giving back the love they received through the work and its music.

The Song Behind the Song

To understand why this remake lands so emotionally, you have to know what “Foggy Road” originally was. Back in 2016, Jinyoung then the leader and main producer of the boy group B1A4, and one of the drama’s central cast members as the “flower boy” scholar Kim Yoon-sung didn’t just appear on screen. He composed a song for the soundtrack, reportedly pouring six hours into directing its recording despite an already punishing schedule, a detail that surprised the OST staff at the time.

That’s the crucial through-line here. This isn’t a case of two actors dusting off an old hit. It’s the songwriter returning to his own composition a decade later, this time stepping up to the microphone himself and bringing along the drama’s leading man to sing it with him. For a piece of music that was born inside the production, having its creator and its star reinterpret it together carries a symmetry that most anniversary releases can only dream of.

Reimagined as a Male Duet

The new “Foggy Road” keeps the aching, wistful tenderness of the original while shedding its overtly sageuk-era coloring. In its place: a fuller, richer instrumental arrangement and a more restrained, unadorned vocal approach. The song has been reborn as a male duet, and that structural change is the point it gives the two men’s contrasting timbres room to trade lines and layer emotion in a way the original never attempted.

Notably, Park Bo-gum didn’t just lend his voice. He personally handled part of the arrangement and played piano on the track, adding an atmosphere distinctly his own. That’s a meaningful creative contribution from an actor better known on the OST front for “My Person” (내 사람) the tender ballad he released for the same drama in 2016, which promptly swept the Korean charts and confirmed that his appeal extended well beyond the screen. Ten years on, he’s not just singing; he’s shaping the sound.

The heart of the remake is the interplay between the two voices. As they hand melody back and forth, Park Bo-gum’s warmth and Jinyoung’s more textured tone weave together to deepen the song’s emotional line offering listeners who remember the drama both a rush of familiar memory and a fresh, lingering resonance.

Why This Reunion Matters

Moonlight Drawn by Clouds (구르미 그린 달빛), known internationally as Love in the Moonlight, was a genuine phenomenon when it aired on KBS in 2016. A coming-of-age youth romance set in the 19th-century Joseon Dynasty, adapted from a hit Naver web novel, it launched Park Bo-gum from promising newcomer to bona fide leading man a performance that, alongside co-star Kim Yoo-jung, earned recognition at the Baeksang Arts Awards. For a generation of international K-drama fans, it was a gateway series, the kind of show that gets passed between friends with the words “you have to watch this.”

That’s why a quiet acoustic remake can feel like an event. The people who lived inside that fictional Joseon are now a decade older, their careers long since diverged Park Bo-gum into film, prestige drama, and military service, Jinyoung into a steady dual track of music and acting. To hear them harmonize on a song rooted in that shared moment is to be reminded of how much time has passed, and how the affection for the work hasn’t.

A Gift, Not a Cash-In

Anniversary re-releases can easily read as commerce dressed up as sentiment. This one deliberately refuses that framing. By channeling every won of proceeds to charity, Park Bo-gum and Jinyoung recast the remake as exactly what they call it a gift to the fans who kept the drama and its OST alive for ten years, and a way of paying that devotion forward.

There’s something fitting about it. Moonlight Drawn by Clouds was, at its core, a story about young people trying to do right by the people they loved in a world that made it difficult. A decade later, its star and its songwriter have answered that theme with a small, real-world echo: a song given freely, made together, for everyone who never quite let the fog lift.
