High School crush

I have a dilemma. There is this boy who I sit next to during class. He is more on the quiet side and everytime I see home my face turns bright red.

I don't really talk to him.

I am a freshman and he is a junior.

He saw me give another boy a hug and kept looking at me weirdly. My friends and teachers also give us weird looks too.

I don't know if he likes more or just thinks I'm weird.

How do I shoot my shot while not being obvious?
