Why does a girl always seem to reply to my qq signature?
It may be a coincidence or you think too much, but it doesn't rule out that she pays attention to you. I have seen many such cases in my life. Boys chase girls, but girls disagree. After a while, girls chased boys. In this case, if you still have feelings for that girl, then continue to the front! If you don't feel it, don't think about it. It's a waste of brain cells.
