Crush Advice ?

I met this guy last year and honestly I really like him, but my problem is he is REALLY CLOSE AND GOOD FRIENDS with my sister and I value their friendship so much because without her I wouldn't have met him. I want to tell him that I like him but I don't want anything to come between their friendship. He walks me to class and lunch and we can talk about anything with each other. I think he sees me more as a friend though.
