What are some signs that a quiet and kinda shy guy likes you?
If he actually tries to make conversation with you and goes out of his way to talk to you
Anything other than direct confession is pure speculation.
actually likes you for who you are and when you are yourself
He would probably stare at u alot and smile. If his face lites up when u talk to him I'd say he's smitten...;)
I completely agree with the chick above ^
