When we look at someone and they look at us, we usually look away. When we like someone, we just keep looking at them. So, I would say, if he/she doesn't look away very fast it means they are interested in you.
He likes you and he wants to get to know you better.Whether through face to face contact, by phone, email........etc.
To know if your crush likes you when you are alone with her, observe to see if she will make any contact.
The only and best way to know for sure is always asking. Otherwise eye contact and smiling can tell much.

Without direct communication, it can be difficult to tell if someone likes you. However, you may be able to gauge their interest through their body language, eye contact, and overall behavior towards you. Keep in mind that it's always best to communicate openly and directly about your feelings to avoid misinterpretation.

Soo...how to know if someone likes you, if you know she likes you?
The only way your going to know if this guy likes you is ask him.
Just all of the normal signs that someone likes you!
If someone likes you and he or she is shy, first find out if that person really likes you. If that person likes you then try to ask that person out. I'm sure it will be fine.
Just ask him. He will let you know with his mouth or his body language.
