She thinks i'm cute but i dont know her. what now?

okey so last week i stayed after school for a study session and i met this one girl( kinda met cause didnt really introduce ourselves or talk). she apparently told my friend (a girl) that she taught i was cute and my friend in return told me..(so much for keeping secrets :p) so does that mean she likes me or is interested in me? i find her attractive but the problem is i didnt even know she existed until week and i dont know what to do now. advise and help, please and thank you :D!
