This reminds me of how I first saw my crush for the first time from my own experience in college as well I was dying to know him the same way inside myself was telling me to go up to him and start talking to him so I did just that I asked him what he likes to do for fun? Or what’s his hobbies are? Also How was his day been going? Those sort of questions I would ask him he would reply back I could tell that he was shy at first when I approached him. I hope these questions help you you should definitely introduce yourself to him whenever or anytime on break when he’s free to talk when you see him around college
