this is the first few paragraphs of my next short story. Alex is a nerd and Isabelle is a spy but he doesnt know that. I'm not sure where to go after this. Help?

Secrets

            Alex walked into the bookstore out of the rain. The store was quiet and warm and smelled of new paper. As he looked around he noticed a girl across the room. She was sitting in a chair reading a rather large book. She was beautiful with long dark curly hair and an angular expressive face. As he watched her she looked over and smiled. What he did not know was that she was there to meet him.

            He was a creature of habit and always went to that book store on Wednesdays looking for a new book that week. She was there to make him fall in love with her. She didn’t know why yet her boss had not told her. As she got up and walked toward him she noticed a look of surprise on his face. She kept it simple with a “Hi, how can I help you?”

            He had come here every week since he moved to Chicago and had never seen her before. As she approached he tried to think of something to say but he had never been good at… well talking. It turned out she worked there which meant she was probably just doing her job by talking to him. This relaxed him a bit and he was able to carry on the conversation without being to awkward. As he was thinking this she reached out to touch his arm. That’s when he realized she was flirting. He was so shocked he stopped in mid sentence.

            He had asked her out to a coffee shop when she got out of work at 5. Perfect thought Isabelle, everything was going to plan.
