This girl keeps shading me?

so it’s been a two months into college and i became friends with the three people i have math with. everything seems to going right except i notice this one girl always has something to say about me each other. it’s like sudden shade but she acts like it’s lighthearted. i’m trying to give her a benefit of the doubt, thinking maybe she’s just too comfortable with me already. but she hasn’t acted that way with the other two and like i said, this has happened every hangout. she also tends to act nice to me. whenever she says something shady, i defend myself. but i try not to sound too defensive because i don’t want to start problems too early. i’m not exactly sure what to do because if i distant myself from her, i’d have to distant myself from the new forming group we made because we all sit together in uni along with walking together after class. i also have no other friends as wll. i just transferred to this college and i haven’t had a healthy friend group in over 3 years. what should i do?
