Also known as Just Roommates, Up to Interpretation, domtext, Girl's Love, Shoujo Ai, and Just really good friends
Female -> female love & female + female relationships.
Should be mostly explanatory when reading the chapter/series.
Does NOT matter what the setting is it just needs to feature love involving (at least) two women. Transgender women are women too.
For stories with extra ambiguity, consider the Subtext tag instead. For stories featuring one-sided love as a side-plot or secondary character trait, use Yuri crush.
