I need guy and best friend アドバイス please

Hi everyone for a couple weeks my friend has been crushing on this guy at school. Just about everyone is crushing on this guy hes a senor he break dances sings and plays ギター and hes good looking. I wanted to be the one who doesnt like this guy. I didnt really like him. but during this week my friend has been trying to talk to him me によって her side. On a days we have the same linch my friend and i but not on b-days. Me and this guy have the same lunch everyday. He always plays ギター and sings when we walk past him. I would always look the other way. I finally looked at him and he smiled at me he didnt turn away he kept 歌う and playing. Then every b-day when i dont have lunch with my best friend he always finds a way to get near me and talk または dance. He also looks like he is going to come and talk to me but then hesitates to and turns around. I kind of like him now ever since he smiled at me. what do i do? Do あなた think he likes me?
