She talks to everyone but ignores me alone—does she secretly like me?

There's a girl who talks to the other guys but not to me. She acts normal when we're in a group, but when we're alone, she barely glances up and then looks back down.
To clarify, she's done things like touch my legs before, agree with what I say or agree with it herself. Recently, she suddenly started smiling at me, but then she went back to barely glancing up.
