I had this exact scenario happen in college. After class this one of my classmates approached and we just started hanging out a lot.

Looking back on it in think she wanted to date. She dropped a lot of hints including one time calling us hanging out a date and then she said well I guess it's not really. Then she talked about how she was trying to find someone to date. But I took all of this literally and was like got it not a date and understood you are looking to date but clearly not me right?

Yeah I was oblivious, worked out though found my wife next year so no complaints.
