Maybe it's subconcious or something. It happened to me with one girl, she'd sing softly whenever I came in the general vicinity, npt rap songs or rock and rolll, just soft songs. This was followed usually by sighing, doing something really big to draw attention and or putting down her head. Any of this sound familar with you seraph? If so, this girl likes you and you have been ignoring her or acting like it. Stop playing games if they aren't neccesary
