It's shown less in later episodes, but she's incredibly sweet and caring, she goes out of her way to help Tremolo on his first day, they go out for lunch and she tries to pay for it, she lets this guy she's known for a day stay in her dorm, she obviously has an incredible amount of guilt and regret for the Cumpetition debacle, she looks after him when he blacks out at the Pink Rose. Even when he comes back to the dorm after the Josy date, she runs over to hug Tremolo and wants to help him process his feelings, despite the fact it clearly made her jealous.
People always bring up her being emotionally reserved for being a bitch, she has a shit family life, her relationship clearly hurts her, she's not going to pour her heart out to some guy she's known for a week.
After leaving up throuple, her concern is Josy and Tremolo, while Josy is I, I, I
Episode 10 after leaving the throuple firmly cemented her as my 2nd favourite MG, probably my 3rd favourite overall. If there's ever a situation J/M split, my first run would absolutely be Maya solo
