What happens when the guy is shy and he is interested?

I’m trying to give and send signals that I’m interested, but he is the shy type of guy too. Keep in mind that this was a huuuge set up with my upper bosses for THE longest time ever. Also, was not aware that he was interested in me. Do I just outright tell him that I’m interested? Or wait till he gives and send the next signal? Cus I have a feeling that we’re taking this sloooow.
