I'm having trouble understanding this boy.

I'm an 18-year-old female and have just started my accounting course at university. Since it's a night class, there aren't many students, but there’s one guy, also 18, who sits in the same row as me. By the second week, we began sitting next to each other because our teacher often asks us to pair up for problem-solving. We hit it off, bonding over being the only freshmen and both feeling a bit lost during lectures. I find him really attractive, and I feel like we have a strong connection. I've been trying to figure out how he feels about me. Here are some things I've noticed: - He opens up pretty easily and engages in conversation without hesitation. - He tends to mirror my reactions; for example, if the professor says something funny and I laugh, he'll laugh too—though his reaction comes a bit after mine, as if he’s waiting for my cue. - He has trouble maintaining eye contact when we’re speaking, but I catch him looking at me when I'm not facing him. - The only time he truly looks into my eyes is when we say goodbye; he waves and gives this adorable little head tilt that honestly makes my heart skip a beat. Even though I usually have a good sense of people’s relationships, I'm struggling to read him. Any advice would be really helpful!
