Stories with reversible couples, couples with non-traditional top / bottom dynamics, and couples where the position is not relevant to the story (and hard to identify).

Includes some characters with traditionally feminine traits. A "non-traditional" top / bottom dynamic is any story where the bottom is not in an ersatz "wife" role.

For example, stories where the shou is younger, "bullied" in bed, described as a cute animal, assigned feminine traits, relies on the gong financially or emotionally, described as less rational, etc, and where the gong is older, sexually dominant, assigned masculine traits, the financial provider, described as more rational, etc would be considered a "traditional" top / bottom dynamic.

Also takes into account some popular danmei specific tropes like younger / older brother, gong cooks (except in some domineering CEO stories), shou is shizun, and so on.
