I have a church crush! what do i do?

So our church doesn't have a Sunday School or club. You just come to the service and once it's finished, you go in peace. No solo-singing, no dancing.
2 weeks ago, when I came to church, he looked at me about 3 times and when we finished church he was literally stretching his neck out to look for me.

I normally stand right at the back. He sits in the middle of the church with his little sister and his mum. I was thinking maybe I could sit on the row behind him, in front, next to him or even on the same row,
so if we did 'Peace Be With You', we could hold hands. Would that work?

I don't know how he feels about me but I need to know. I need some advice so I can impress him.
