Love or just for fun?

I know it's not possible~ You said before, you won't fall for your close friends~ But why I could sense that you had feelings for her? Why your every actions lead me to believing that you actually had feelings for her? Your every body languages, every 眼神 when you look at her, every status about her made me believe that you already fall for her~~ But why each time we talked about it, you just wouldn't want to tell the truth~ Is it really love or you're just playing around with her feelings?
