I have to disagree with your comment. Everyone is a little intimidated by someone they're attracted to. It's okay to be nervous and want to get things right. There is always the real possibility that if you fuck up, she's going to lose interest or be frightened off. This applies to most social situations, especially when the stakes are high (relationships, career opportunities, etc). So, I can understand how ThatFanficGuy wants to do this compliment thing right, and these kinds of questions are exceptionally common from those less experienced in relationship etiquette. He shouldn't rely on it alone for courting, but there is no shame in gathering more information to give it your best shot. I think you are reading into this post too much; ThatFanficGuy's relationship to the girl is not mentioned. Plus, asking an insecure person if it's "reasonable" for someone else to find them attractive will very, very rarely get you an objective answer.
