Cutie in class 😬

Ok so I have this class called seminar with the same people for the past 3 semesters and we still have 3 more semesters of it. There’s this guy that I’ve developed a crush on so what’s the best way to “shoot my shot” with him? Like we have a Snapchat streak and we talk in class but I’m not even sure if he’s even really interested so really I’m wondering what should I say so that if he’s not interested it won’t make things awkward in class and I won’t hate going there for the next 3 semesters. At this point I’m tired of seeing if he’ll make the first move and I’m ready to take the initiative but at the same time I’m worried about rejection and awkwardness

Thanks x
