If he like you or interested in you, he would tell you. THat's usually most man grown up in U.S would do.
A pair of attractive eyes could not mean the way you think. He might like you very much so he stearing at you a lot. But if he does like you enough, as a adult, he would do something. Chinese girls are so shy and most of us might like someone and put inside for long time. But that's not the way American people do. They pretty much straight forward. Or maybe you can go to ask him tell him that you interested to him . See what he say. You will figure that out.
