You won't know unless you ask. If he says no, say thanks and walk away with your head held high.
How do I tell my crush I like him? What If he says no. I'm stuck and he is always with his friends only sometimes he is alone. Help please!!!!
Do you have any friends that know him? A message through them would be easy. You could also go up, introduce yourself, tell him he's cute, and then ask him to hang out sometime.
If you get rejected? It happens and it stings. Fortunately, there are billions more men out there. :D
