Got any examples? Alphys is very insecure in general, and insecure about liking Undyne because she thinks Undyne is cooler than her. I don't think her being a woman had anything to do with it

I mean I get your angle here, but the whole game is about helping people work out their emotions and improve their relationships with each other. I don't really think a super-awkward romance is out of line in that context, lesbian or no.
