Cancer girl wants to be a secret admirer for scorpio man, any ideas?

If you know something about astrology or have insight on the issue id love to hear from you. I'm a cancerian 20yr old,interested in setting up a secret admirer/mystery woman scenario with a man of particular interest to me. I know scorps are natural detectives so i dont know how long it would last but im curious on ideas that are both lighthearted,fun and y. I dont want him to feel creeped out or stalked. Ive never been interested in a guy enough to want to do this so truth be told i honestly dont know where to start! All i know is i want it to be y,and maybe id want him to have to meet me somewhere. He's in his early thirties if that makes a difference.
