Flirty moves on this guy I like?

So ok I like this guy (duh). He's INCREDIBLE. He's like a complete package. Voice, looks, he plays in a band, he dances, loyal, honest and down to earth We met last week but we are in Annie together right now so I spend 5 hours a day with him everyday of the week. I know him pretty well. He got assigned to play my boyfriend in this one song. So we have to like freeze when warbucks and grace sing and we have to stare into eachothers eyes. He always is looking straight at my lips or my eyes. ALWAYS. So he always is saying hi to me and stuff so I think he's interested but I'm not sure. so I need some cute little flirty ways to get his attention when were talking. He stares at me sometimes too I don't wanna stare to often or for too long cuz I'm not good at flirty staring
