Ace was willing to bet he cared a lot more about Coral than she cared about him. Or, at the very least, that he thought of her more often. She was the one constantly writing or drawing on herself, after all. It would be hard not to.
Despite knowing she would be a distraction that would likely get in the way of his goals, he wanted to meet her. She would never go for it though considering how high her walls were.
They were soulmates. Given the chance to know each other properly, they were perfect for each other. She had to know that but still kept her distance.
Why was that? Ace knew his reasons for not wanting to get involved but weren't girls supposed to be into romance? Maybe she was one of those "free love" nuts who went around dating as they pleased and didn't put stock into soulmates.
