At the beginning of the game I though it states somewhere that you're pretty close to Alice, but not recently. I assume it's due to her asshole boyfriend and all the shit since Darci left. It's been a while since my last start, but I remember that we're close to Alice and barely know Alyssa, which is why I found it odd how that switched.
Yeah I thought so as well but when I went back and replayed her scenes the way they talk to each-other in the library and on the walk home, it's a scene where they're each feeling the other out and getting to know each other a little. Friends generally know where each other live for example. Alice had no clue the MC lives close to her.
When you rescue her from her boyfriend the bf asks if the MC is one of her stupid friends, something along those lines. MC responds nope, she's just a classmate.
They've likely seen each other around school, but were never really close.
Only reason I even went back to check those scenes is my neighbors were screaming at each other till around 3am last night, keeping me awake. As I listened to them argue it brought to mind this conversation about Alice and her boyfriend. And something in the back of my mind kept nagging at me that something was off about thinking of her as a friend. So figured why the hell not, I'll skip through and check real quick, not like I was going to get to sleep again until the shitty neighbors shut the fuck up anyway.
