BL, yaoi and danmei are terms readers may encounter when exploring stories about romance between male characters. They overlap, but their use depends on language, region, platform and community.
BL, short for Boys' Love, is widely used as an umbrella term for romance-focused stories featuring male-male relationships. It is used across different media and markets, although the exact meaning can shift between communities.
Yaoi is a term associated particularly with Japanese-origin media and fandom contexts. Its use has changed over time, and readers may use it differently depending on whether they are discussing manga, fan works or older genre labels.
Danmei is commonly used for Chinese-language BL fiction and related media. It has its own literary and publishing context, and readers often use the term when discussing Chinese web novels and adaptations.
These labels should not be treated as perfect translations of one another. They can signal different cultural and publishing contexts, even when the stories share themes. When in doubt, follow the terminology used by the author, publisher or community being discussed.
The most useful approach is to understand the context rather than assume that every BL story belongs to one tradition
