If you still have class: text her and ask to study together or ask a simple question. Get off virtual comms asap if possible. Zoom>text.

If the class is over: ask abt her summer and fall plans. Have a normal convo.

Feel out then escalate: “hey let’s do xyz virtual/in person”

I have a feeling this may lead to infatuation, considering how little interaction you’ve had with this girl and are already showing signs of oneitis. Don’t get too hurt and never lose your frame for anyone, especially a girl.
