Would this make me look like a stalker?

I feel like something could happen with this girl. We’ve had two classes in a row together so far. In our first class she was very talkative and I was going to my seat once and I guess she had been talking to a friend nearby and she stopped and stared I just remember her mouth being slightly open when she did it lol and it looked pretty distracted by me lol.
The next semester, we had another class and I’ve seen her sneak a few glances. I have this thing where she maybe thinks I’d be rude or is scared to talk to me because I’ve been told I look intimidating and I’ve gotten that I’m pretty a lot too. I’m also very feminine so she prob doesn’t think I’m gay when I’m actually bi
( I know she likes girls because she’s said it in class )
Also she got a haircut and it was drastic and when she showed it to the class and took off her hat, she looked at me first to see my reaction.
Once she did sit next to me because her usual seat got taken and she looked really awkward the whole time lol and she didn’t talk to me. It’s weird because she’s outgoing around certain people but very laidback and barely talks. She was fidgeting a lot too.
Also on the last day the professor commended a point I made in my essay and he asked me to explain and I did. While explaining it, I made a new point and she was like “hmm” very loudly because she was agreeing.
So she had an acquaintance that she always talked to in class and they’re very loud. So I heard her say that she started working at this cafe downtown that I’ve been past a few times but frequent the area.
The semesters over ( I might have another class with her again ) but I want her lol and I’m debating if I should casually go to her job one day. I’ve been wanting to go there anyways lol. I don’t want to sound like a stalker lol I’m not but I think it would be cute. Could she be interested? So I only have her school email should I have emailed her school email or should I try and go to the cafe?
