Revisiting the Story Through Song: 7 AI BL OST Music Videos

blaiva Editorial Team · November 2, 2026

In AI BL, an OST music video is more than a promotional clip. Scenes cut from the main series, moments not yet revealed, and sometimes even alternate settings that differ from the original all fit into a single song. In just 3 to 4 minutes, you can get a full taste of a work's mood, making it great as an introduction before watching the main series, or as a way to settle the lingering feelings after. Beyond the OSTs for "Agarwood" and "Love of Unknown Origin" that we covered earlier, here are more songs worth a listen.

Flower Moon — The Flower Blooming on the Palace Wall OST

Moonlight Echoes Drama · about 3 min

This historical-drama OST sings of a forbidden love blossoming under the moonlight. The music carries over the mood of the original, which builds emotion through glances rather than dialogue, so you can get a sense of the story even if you haven't seen the main series.

Don’t Be Like Them

Ajaedal · about 4 min · Fantasy

This fantasy music video tells, through song, the story of a silver-haired elf locked in a golden cage and the crown prince who stops in his tracks before it. The theme of a fear that doesn't vanish even once the cage door is open runs through both the lyrics and the scenes. The channel states that both the music and the visuals were made with AI.

Corner — The Dog That Ran Away OST

블루룸 · about 3 min

This is the OST for "The Dog That Ran Away," with human-written lyrics sung by a virtual singer. It carries on the desolate air of the original, which opens on a rainy night, so it hits harder if you listen after watching episode 1 of the main series.

Farewell, Please — Earlobe MV

녹턴 (Nocturne) · about 4 min

A song of parting, where one simply nods before someone who says this is the end. The characters from "Earlobe" appear, but in an alternate setting separate from the main series, so there's the fun of imagining a different story for the same people.

Breath — How Could I Not Remember OST

달빛서가 · about 4 min

A breath that grows clearer the closer you get, a heart that reached them before words could. This original music video captures the story of Kang Taeheon and Yunsu through song and visuals. The direction, which conveys the warmth of their relationship in such a short time, is a highlight.

Beyond the Flames — Ash and Gold OST

MAKEMAKE4 · about 4 min

A song capturing the feelings of Adrian and Leon seeping through the flames. Deleted cuts that episode 1 didn't show and moments yet to come are tucked away throughout, so for fans following the series, it reads like a clue to the next episode.

Pretending It's the First Time, Pretending Not to Know — Agarwood Side Story OST

Late Blue Night · about 3 min

This is the OST for a contemporary side story, not the historical main series. It captures the moment when strange yet familiar gazes cross in music, letting you feel in song first the side story's premise of the same two people meeting again in a different era.

Three Ways to Enjoy OSTs More

1. Turn on the subtitles. Most OST videos come with lyric subtitles. Watching how the lyrics interlock with the scenes reveals the intent behind the editing.
2. Pair it with the main series episode. The description box often says which episode's scenes the OST was made from. Watching right after that episode carries the emotion through.
3. Look for the deleted scenes. Scenes absent from the main series often appear only in the OST, and among fans they're treated as a kind of bonus video.
