A guy question ? ;/

Hm .. theres this really nice guy @ my school
He doesnt know me, I know him by my cousin . They're best friends
At graphics I made him a photograph with iloveyou inscripted in it . Im very happy he still has it
I really like him, when I see him at school. We look at each other like we know one another already, and he always smiles.
Do you think i should introduce myself to him ?
