Oh goodness, across the series there's some ongoing relationships and some one offs, and the trans content's varied and all over the place throughout because it's an anthology series. But off the top of my head there's multiple transfemme/cis femme pairings, a transhet (MTF/FTM) pairing, a transfemme/multiple cis femme poly quad, a transfemme/transmasc lesbian pairing, and some other stuff that gets complicated to classify along the way. :)
