Please help, i asked once but no one helped:(?

Well there's a guy in my drama class and i feel like there's a really strong connection between us.for some reason, i always end up acting with him in pair. Then after that, he teased my bestfriend and me in a nice way. That happened about 2 or 3 times. My friends noticed that maybe he likes me, he showed it pretty obviously, i caught him looking and staring at me all time, and smiled at me when i didn't look

We never talk out off work stuff though, I see him everywhere i go in school, that just...freak me out becuz of the coincedence( AS i think it is)

But the thing is, my bestfriend is a very friendly girl, i am not. Whenever he teases us,she was always the one who responded.

I wanna talk to him real bad,but there's something that holds me back.

I dont wanna show my interest now though, i wanna start a friendship with him

Please helpppp, how not to be shy in front of himD:
