Flirt.
No, you simpering coward.

text or flirt.
Be nice to him by doing random acts of kindness for him.
text him
You express your feelings toward him but not too much
Show him!... You should do flirty stuff like play with his hair, kiss him, or constantly touch him.
Talk to him
That's difficult without coming right out and saying that you like him.
Simple... Flirt in your own way Just to let him know "Hey, I like you..." without saying it. Good luck!
Most likely he's telling you he likes you.
