So, the romance is only between lesbians?
I can only speak for the routes I played, which again were a long time ago.
I haven't played it yet, but I think the emperor is a good romantic partner as well, but there are some caveats for his route:
The MC drinks a love potion and there is the whole harem competition dynamic, so while the end result might be nice, it isn't exactly a "normal" relationship
There are also several other male characters with who the MC can have fully consensual relationships with, but most of their dynamics are more kinky than romantic imo:
The baker is a bossy horndog, and the male slave alternative to Lea likes to reverse the master/slave roles with his mistress
And there are also some male characters that don't really seem to want to take the advantage of the MC as much as they accidentally do it, but don't seem like bad potential lovers.
Due to her being a shapeshifter the MC is easily influenced, so she gets extra affected by things like pheromones from the Minotaur chieftain, and the male shapeshifter she meets later into the story, the first guy is probably not aware of the exact extent of his natural effects over the MC, and the later while aware seems to think that is just natural for their kind and the MC is kind of silly for resisting it if she chooses to do so.
I agree that on average the lesbian romantic relationships seem a bit more developed, but there are at least a couple of alternatives among the male characters.
