She’s pretty naive and immature but then again, like the caption says: she’s just out of highschool, a freshman in college. (Could be wrong about the time frame cause I don’t remember how long this relationship has been going on). I don’t expect her to act all mature and have super high intelligence. It doesn’t help that she literally has no friends or family to go to for advice. The only advice she gets is from blondie that also wants to hook up with her. If blondie approached her and got to know her through a friendship first, he’d be more reliable. But so far he’s technically similar to the black haired guy. Hot and rich, looking to sleep with her, not knowing her well.
