Late Blue Night: How to Expand One Work in Three Directions

blaiva Editorial Team · November 2, 2026 · Compiled from the published works and description boxes

Late Blue Night is a channel known for 〈Chimhyang〉, a Joseon-era period-drama AI BL. What makes this channel interesting is that, rather than increasing the number of works, it deepens and expands a single story in three directions: the main series, the OST, and the side story. On blaiva alone, more than ten of its videos are featured, and two of its OST music videos have each been played over 700,000 times.

Direction One: The Period-Drama Main Series 〈Chimhyang〉

The trailer opens with a single line, "It was dull. Until yesterday.", and the tip of a needle passing over silk. The making of clothes sits at the heart of the story, and the distance between the two leads, Seojin and Doha, closes stitch by stitch, like sewing. Emotion is conveyed through glances and fingertips rather than big events, which suits the still beauty that AI video renders so well.

Direction Two: OSTs Made from Deleted Scenes

The OST videos on this channel are not mere music videos. They weave together cuts and B-roll trimmed from the main series, showing moments the main series never revealed, set to song.

One Stitch Closer

The first OST, made from deleted cuts and B-roll of Episode 1. The song follows those first moments of drawing near, almost touching but not quite.

Where the Scent Lingers

Seojin's theme song, re-edited from unreleased scenes of Episodes 3 and 4 through Seojin's eyes. The video shows how the same scene reads differently depending on whose eyes you see it through.

Colored by Light

The duet by Seojin and Doha that closes out Season 1. It features unreleased scenes from Episodes 5 and 6, wrapping up the lingering feelings of the main series once more.

In blaiva's production-info classification, a music generation tool was used for the OST music. Even as both the visuals and the music make use of AI tools, the power of editing stands out, since a person chooses which scene goes with which song.

Direction Three: The Modern-Day AU Side Story

There is also a parallel-universe side story that is not connected to the period-drama main series. In it, Seojin is a troublesome fencer and Doha is his sponsor, and the two meet again. As episode titles like "Pretending It's the First Time, Pretending Not to Know," "Night, Rain, Alcohol," and "If You Don't Like It, Tell Me" suggest, it unfolds in a modern way of speaking the feelings that went unspoken in the period drama. A further plus is that you can enjoy it on its own without having watched the main series.

Some Bonds Change With the Times (Side Story EP.1)

The start of the side story, which portrays a bond that reconnects across a change of era. Viewers who know the two leads of the period-drama main series will be glad to find the gazes familiar.

The Order to Watch This Channel

1. Check the mood with the trailer
2. Main series → the OST that matches each episode
3. If you liked it, move on to the modern-day side story

After watching all three directions, you'll come to feel that an AI drama can expand into a whole world rather than staying a single video.
