I need boy advice

Sade
Ok so here's the situation. This guy named Bryan that I went to high school with. He's weird ok so everytime he would see me he would stare at me and he knew I liked him because my friend was friends with him. So everytime we seen each other he would have eye contact every single time. And my friend said when he told him that I liked him he smiled is that good or bad? Ok so I need your opinion is this a good or bad sign? Was he interested?
