the easiest way is to ask.
You'll know if he likes you if his dick goes hard when you bend over..
when his friends aren't around he talks to you and flirts with you. this means he likes you, but does not want to let his "popular" friends know.
My best advice to you is to ask him yourself
erm hey my name amanda and im going with this super cool guy called dan and he tottally would help you with this you know ask him for his digits and he will call your cell like totally im super excited for you and hope he likes you, good luck hehe
iam in love with this guy but i do not know if he likes me or some other girl
when he says he likes you.
If a guy likes you but you don't know him he may look at you or walk by you whenever possible.

The only way to know if a young man likes you is to go up to him when he is alone and perhaps ask him out to a popular cafe so you can get to know each other better.
just tell him I have the same problem but I'm not super popular and boy do I waish I had an anser
Not sure how you expect someone to magically know something.
What do you do when a popular shy guy you know like likes you? Well, i think u should say something to him (eventually). As he walks down the hallway start by simply smiling. sit next 2 him in lunch, acknowledge he loves u without openy yelling it out that he likes u.
