Gross overuse of "female" instead of MC's name

MC who doesn't seem to mind that the MMC doesn't feel the need to explain anything to them and treats them like a child.

MMC praising MC for being a "clever female" after MC makes one obvious logical conclusion.

The two characters have literally no foundation to build a good relationship on other than sexual attraction. They don't like each other.

Inner monologue reinforces the idea that the two species are so incredibly different when literally the aliens are just grayskinned humans with pointy teeth and a little more strength (and sometimes horns).
