As far as Maya being a tease, I think it's hard to judge at the moment. When the MC suggests explaining she's not into boys to the HOTs she's pretty emphatic she's never revealing that "again." There's also her diatribe about being judged.
If whatever drove Maya and Josy apart is both believable and harsh, I think it can sell Maya as a well-meaning but introverted young woman scared of losing the only good thing to happen to her in months.
She just can´t handle conflicts.
Dad is mad cause she´s into girls? Avoid Dad, go for that free Tution with the HOTs (although she´s clearly uncomfortable with them)
Girlfriend wants to move away? Yeah sucks, but whatever, let her leave. (She has to know it at the time MC knows it, still MC visits her while she stays at her Dormroom)
Girlfriend joins College so she can´t avoid her anymore? Let´s talk for an hour and everything is fine again.
MC is mad at her? She needs to talk it out (seemingly she doesn´t really care, if MC has feelings for her or she for the MC. If he´s a nice guy she takes the risk and tells you "Let´s never fight like that again", if he´s a bad guy conflict is bound to happen so she doesn´t risk it, Friendship works just fine either way)
She goes with the flow. Don´t piss anyone off, avoid conflict, run away from problems. Only facing it, when she can´t run away anymore.
