Hi there I’m 20F and I have this huge crush on this guy in my class! I really want to smash lol!

It’s a small 20 person lecture and it’s about halfway through the semester so it’s a little weird to go up to someone at this time in the class.

How can I approach this ? ??? I don’t even know his name so I can’t find him on social media :(

Should I approach him with a compliment or ask about the class?
