Can honestly I say I did not get that sense at all. I am a huge Maya fan, so maybe I'm a bit biased, but there were several moments, for me, that make it seem like she really likes the MC a lot.
For starters, she seems really nervous about having sex with him, and it seems to be more about wanting to please him than it is about actually doing it, almost as though she's worried that if she doesn't do it right then he won't like her as much anymore, which is kinda cute. She also imagines that "Mr Dildy" is him and it seems to turn her on a lot more.
Then there's the Gender Studies class where she says "I like you" and when the MC replies back, "I like you too", she breathes a sigh of relief, almost as though she was worried that he might not say it back and she's happy he did. Next we have the 2 moments in the library, the one where the MC is practically fingering her and afterwards she kisses him in public which is a very big step and the one where she holds his hand and gives him a nice smile.
Finally, we have the "threesome" scene and she is very much enjoying herself and loving the feeling of him being inside her. So all-in-all, I'd say that this episode did a lot to show that Maya is really falling for him, but it did also reaffirm that Josy really likes him too because she clearly missed his dick.
