How can I tell if this asian girl likes me?

There is this cute little asian girl thats very quiet and shy that goes to my college. I wanted to talk to her, so I made up some bs opening line. I was like "hey are u in my music cl? (which she wasn't)" and surprisingly she said yes she was. We had some small talk, but she had to leave cause her friend came. The next time I saw her, she was sitting with a friend in a cafeteria. I went up to them and greeted her and had a little more small talk. After that I went away to sit with one of my friends a few tables away, and I noticed that her friend was eyeballing me from afar. A third time I saw her while going down an escalator, and I asked how she was and what she was doing since her cl just ended. She got really shy and started to look away or something. I guess she thought I was going to ask her out or something. So she quickly said that she had to go do something and scurried off. So I'm wondering if she likes me but is too shy.
