Act like you would normally act any other time - don't try to be something you are not.
You don't. 'Getting a boy to like you' means changing yourself so that the boy will like you. Be yourself and you'll get a boy who likes you for you, without you having to change yourself. and he might like you the way you are anyway, so just be yourself. Talking to him would be a start as well!
Be yourself.
