blaiva Editorial Team · November 2, 2026

The titles and descriptions of AI BL videos are full of terms that can look unfamiliar at first. That's because long-standing BL genre vocabulary is mixed together with new words that have emerged from AI video production. Here are 20 frequently seen terms, explained with meanings and examples.

Story and Genre Terms

Hyeomgwan (Enemies-to-Lovers)

Short for "hyeomo gwangye," meaning a relationship of hatred. A story in which the feelings of two people who hate or compete with each other change. Example: the racing rivals story "Brake ONE."

Reunion Story

A story that begins when two people who broke up meet again several years later. Misunderstandings and lingering feelings are the core. Examples: "Dokbae" (Poisoned Cup) and "Love Me, Hate Me."

Mutual Feelings

A state in which both people like each other. "It turned out to be mutual" is often used as the twist in unrequited love stories.

Contract Marriage / Love After Marriage

A story in which two people marry for practical reasons rather than love, and feelings develop afterward.

Omegaverse

A fictional setting that divides people into Alpha, Beta, and Omega. Conflicts such as hiding one's status or struggling against instinct often appear.

AU (Alternate Universe)

A parallel-world story that moves the original characters to a different era or world. Example: the modern-day side story of the historical drama "Chimhyang" (Agarwood).

Side Story

A story outside the main plot. It covers the time after the main story, the past, or an AU.

Historical Drama / Gopung

A story set in a historical period. In Chinese-language works, the classical Eastern style is sometimes called "gopung" (ancient style).

Beastman Story

A fantasy featuring characters with animal traits or instincts. Example: "Jongui Heogi" (Hunger of the Species).

Rom-Com

Romantic comedy. A story that has both laughter and fluttering hearts.

Video Format Terms

Short Drama

A drama format made by stringing together many short episodes, each one to three minutes long. It is especially common on overseas channels.

Full Version / Binge Cut / Compilation

Multiple episodes combined into one video. You can watch all the way to the ending in one go.

Teaser / Trailer

A short video that shows the mood before the main series is released.

OST Music Video

A video that sets scenes to a work's theme song. In AI BL, it often includes deleted scenes.

B-Cut / Deleted Cut

Scenes that didn't make it into the final edit. They are often released as OST or behind-the-scenes videos.

AI Production Terms

Generative AI

AI that creates new images, videos, and music based on descriptions such as text or pictures.

Prompt

Text that tells the AI what to create. It describes things like scene composition, lighting, and characters' expressions.

Image-to-Video

A method that turns a still image made beforehand into a moving video. It is often used to keep characters' faces the same from episode to episode.

Character Consistency

Making the same character look like they have the same face across multiple scenes. It is considered the hardest part of making AI dramas.

Virtual Singer

A singer who doesn't actually exist, with a voice created by AI. You can see them in OST videos.
